I tried running this sample project which uses MapR.
I tried executing the class ml.Flight in the sandbox and from the below line,
val spark: SparkSession = SparkSession.builder().appName("churn").getOrCreate()
I got this error.
[user01#maprdemo ~]$ spark-submit --class ml.Flight --master local[2] spark-ml-flightdelay-1.0.jar

I'm new to Scala/Spark and any help is welcome. Thanks in advance.
I think you are using or exporting a different python version of spark-submit.
For example:
/opt/mapr/spark/spark-2.3.1/bin/spark-submit

I'm getting the following error when running spark-submit on Gitlab.
This works locally, but not on Gitlab.

I'm trying to set up the Hive integration with Flink as shown here. I have everything configured as mentioned, all services (Hive, MySQL, Kafka) are running properly. However, as I start a Flink SQL Client on a standalone local Flink cluster with this command:

I get a ClassNotFoundException: org.apache.hadoop.conf.Configuration...

Do you have any hint about what I'm missing? I have all my Hadoop libraries on my Classpath and I don't understand why this class is missing...
I'm using Flink 1.10 and Java 8
Also, this line in the log file makes me wonder if it really my mistake:
2020-04-01 11:27:32,776 ERROR org.apache.flink.table.client.SqlClient - SQL Client must stop. Unexpected exception. This is a bug. Please consider filing an issue.
Thank you in advance!
if you not add the HADOOP_HOME in you env, you can export the HADOOP_CLASSPATH, before run the ./bin/sql-client.sh embedded
export HADOOP_CLASSPATH=`hadoop classpath`

The problem is that Hadoop 2.7 is incompatible with Java 9/10.
I had the same issue and solved it by downgrading to Java 8.
Check the answer by VK321 here, if you are unsure about how to downgrade and get it to work:

I have been struggling for a couple of hours to solve this problem but couldn't figure out. Can someone help me out? Thanks!
Try installing the Java 7 JDK and you may have better luck. Although the release notes for Scala 2.10.2 seem to be missing, 2.10.4 doesn't support Java 8:
New ByteCode emitter based on ASM
Can target JDK 1.5, 1.6 and 1.7
Emits 1.6 bytecode by default
Old 1.5 backend is deprecated
...and even 2.11.x only has experimental Java 8 support:
The Scala 2.11.x series targets Java 6, with (evolving) experimental support for Java 8. In 2.11.1, Java 8 support is mostly limited to reading Java 8 bytecode and parsing Java 8 source. Stay tuned for more complete (experimental) Java 8 support. The next major release, 2.12, will most likely target Java 8 by default.
Also see: Can I use java 8 in an mixed scala 2.10 / java project built by sbt?
