Implement a java UDF and call it from pyspark - java

I need to create a UDF to be used in pyspark python which uses a java object for its internal calculations.
If it were a simple python I would do something like:
def f(x):
return 7
fudf = pyspark.sql.functions.udf(f,pyspark.sql.types.IntegerType())
and call it using:
df = sqlContext.range(0,5)
df2 = df.withColumn("a",fudf(df.id)).show()
However, the implementation of the function I need is in java and not in python. I need to wrap it somehow so I can call it in a similar way from python.
My first try was to do implement the java object, then wrap it in python in pyspark and convert that to UDF. That failed with serialization error.
Java code:
package com.test1.test2;
public class TestClass1 {
Integer internalVal;
public TestClass1(Integer val1) {
internalVal = val1;
}
public Integer do_something(Integer val) {
return internalVal;
}
}
pyspark code:
from py4j.java_gateway import java_import
from pyspark.sql.functions import udf
from pyspark.sql.types import IntegerType
java_import(sc._gateway.jvm, "com.test1.test2.TestClass1")
a = sc._gateway.jvm.com.test1.test2.TestClass1(7)
audf = udf(a,IntegerType())

EDIT: I also tried to make the java class serializable but to no avail.
My second attempt was to define the UDF in java to begin with but that failed as I am not sure how to correctly wrap it:
java code:
package com.test1.test2;
import org.apache.spark.sql.api.java.UDF1;
public class TestClassUdf implements UDF1<Integer, Integer> {
Integer retval;
public TestClassUdf(Integer val) {
retval = val;
}
#Override
public Integer call(Integer arg0) throws Exception {
return retval;
}
}
but how would I use it?
I tried:
from py4j.java_gateway import java_import
java_import(sc._gateway.jvm, "com.test1.test2.TestClassUdf")
a = sc._gateway.jvm.com.test1.test2.TestClassUdf(7)
dfint = sqlContext.range(0,15)
df = dfint.withColumn("a",a(dfint.id))
but I get:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)

and I tried to use a.call instead of a:

but got:

Any help would be appriciated.


I got this working with the help of another question (and answer) of your own about UDAFs.
Spark provides a udf() method for wrapping Scala FunctionN, so we can wrap the Java function in Scala and use that. Your Java method needs to be static or on a class that implements Serializable.
package com.example
import org.apache.spark.sql.UserDefinedFunction
import org.apache.spark.sql.functions.udf
class MyUdf extends Serializable {
def getUdf: UserDefinedFunction = udf(() => MyJavaClass.MyJavaMethod())
}
Usage in PySpark:
def my_udf():
from pyspark.sql.column import Column, _to_java_column, _to_seq
pcls = "com.example.MyUdf"
jc = sc._jvm.java.lang.Thread.currentThread() \
.getContextClassLoader().loadClass(pcls).newInstance().getUdf().apply
return Column(jc(_to_seq(sc, [], _to_java_column)))
rdd1 = sc.parallelize([{'c1': 'a'}, {'c1': 'b'}, {'c1': 'c'}])
df1 = rdd1.toDF()
df2 = df1.withColumn('mycol', my_udf())
As with the UDAF in your other question and answer, we can pass columns into it with return Column(jc(_to_seq(sc, ["col1", "col2"], _to_java_column)))


In lines with https://dzone.com/articles/pyspark-java-udf-integration-1 you could define UDF1 with in Java using
public class AddNumber implements UDF1<Long, Long> {
#Override
public Long call(Long num) throws Exception {
return (num + 5);
}
}
And then after adding the jar to your pyspark with --package <your-jar>
you can use it in pyspark as:
from pyspark.sql import functions as F
from pyspark.sql.types import LongType
>>> df = spark.createDataFrame([float(i) for i in range(100)], FloatType()).toDF("a")
>>> spark.udf.registerJavaFunction("addNumber", "com.example.spark.AddNumber", LongType())
>>> df.withColumn("b", F.expr("addNumber(a)")).show(5)

How to sort values (with their corresponding key) in mapReduce Hadoop framework?

I am trying to sort the input data I have using Hadoop mapReduce. The problem is that I am only able to sort the key-value pairs by key, while I am trying to sort them by value. Each value's key was created with a counter, so the first value (234) has key 1, and the second value (944) has key 2, etc. Any idea on how I can do it and order the input by values?

MapReduce output by default sort by key, and to sort by values you can use Secondary Sort.
Secondary sort is an one of the best technique to sort the reducer output on values, here is one complete example.

The code doesn't work. I've seen many, many samples like this on hacked WordPress sites. This is resemblant of older code I used to see a lot 3-4 years ago. Probably remote code injection (allows them to run arbitrary PHP code sent in POST requests.
Because the offsets used to pull function names out of $ghacbiaz are wrong, it results in:
PHP Fatal error: Call to undefined function fpg)% () in ...
And from experience, if you've found one of those, there are many more. This type of code may be injected into lots of files in the site.
EDIT: I recall in the past finding a lot of these samples and analyzing a few and also found them to decrypt incorrectly.
This is what the code looks like (but doesn't work because the obfuscated code doesn't line up with the decryption:

The function lmnuklsld it creates would create executable code out of $ghacbiaz and then execute it, but it returns garbage.
Most likely the function of the obfuscated code is either a webshell, or simple code to call eval() on code they would sent remotely, for example they'd call the script with $_POST['some_code'] = 'malicious php code here'; which would then get passed to eval, essentially allowing them to do all kinds of things.

HashMap keeps returning null value for no obvious reason

I have a hash map and an ArrayList. Both of them are populated as I have tried to print them out and it works fine. The arrayList contains MeterNumbers (MeterNumber is the key of the HashMap). The map contains MeterNumbers for keys and String for values.
What I want to be able to do is, get the String value from the the hasMap given the MeterNumber key which i will provide from the ArrayList. I don't think I need to check if it exists there coz I know it does for sure.I have tried all I can to get the value but it keeps giving me null values. Here is my code.
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
import java.util.Scanner;
public class Try {
static Map <MeterNumber, String> map2 = new HashMap <MeterNumber, String>();
static ArrayList<MeterNumber> blackOutMeters = new ArrayList<MeterNumber>();
public static void main (String args[]) {
try {
Scanner sc2 = new Scanner(new java.io.File("meters.txt"));
Scanner sc3 = new Scanner(new java.io.File("outages.txt"));
while (sc2.hasNextLine()) {
String transformerId;
MeterNumber meterId;
String line = sc2.nextLine();
String[] array = line.split(" ");
if (array.length>3){
transformerId = array[3];
meterId = MeterNumber.fromString(array [0] + array [1] + array [2]);
map2.put(meterId, transformerId);
}
}
// System.out.println (map2.values());
while (sc3.hasNextLine()) {
MeterNumber meterId;
String line = sc3.nextLine();
String[] array = line.split(" ");
if (array.length>2){
meterId = MeterNumber.fromString(array [0] + array [1] + array [2]);
blackOutMeters.add(meterId);
}
}
for (int i = 0; i <blackOutMeters.size(); i++){
String s = map2.get(blackOutMeters.get(i));
System.out.println (s);
}
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
}}
file format for meters.txt is:

Thank you in advance.

You need to implement hashCode and equals for MeterNumber
Otherwise Java has no way of knowing how to compare your objects

Eclipse [] is an unknown syslog facility error

I'm trying to execute a program in eclipse and I when I click run I see this in the console output:
[] is an unknown syslog facility. Defaulting to [USER].
/
"Failed"
Any ideas?

It looks like that error is coming from org.apache.log4j.net.SyslogAppender, and that you've tried to set a bad facility name. Go take a look at your appenders and how you are setting them up.
414 public
415 void setFacility(String facilityName) {
416 if(facilityName == null)
417 return;
418
419 syslogFacility = getFacility(facilityName);
420 if (syslogFacility == -1) {
421 System.err.println("["+facilityName +
422 "] is an unknown syslog facility. Defaulting to [USER].");
423 syslogFacility = LOG_USER;
424 }
425
426 this.initSyslogFacilityStr();
427
428 // If there is already a sqw, make it use the new facility.
429 if(sqw != null) {
430 sqw.setSyslogFacility(this.syslogFacility);
431 }
432 }

Error in JNI method returning ArrayList of Points

I'm trying to use JNI to import a c++ library that I will use in my java project. I have successfully gotten the library method to be called and am trying to return an ArrayList of Point objects from the JNI function. However, I'm getting an error with a rather vague description ('Problematic frame:
V [libjvm.dylib+0x30bab5] JNI_ArgumentPusherVaArg::JNI_ArgumentPusherVaArg(_jmethodID*, __va_list_tag*)+0xd
'). I have no clue what's going on, does anyone know what's going on or how I should interpret this console output? I can attach the log file if anyone wants it.
Console output:

Function addfrom class ArrayList has return type boolean not void so in c code you have to call CallBooleanMethod from env instead of CallVoidMethod.
Edit: And you need to correct the signature of the add method as well.

You need to change the method signature for "add" element in arrayList as below:
jmethodID add_arraylist = (*env).GetMethodID(arraylist_class, "add", "(java/lang/Object)Z");
instead of
jmethodID add_arraylist = (*env).GetMethodID(arraylist_class, "add", "(java/lang/Object)V");
