I have mapped a column in Mysql DB to enum in java. Have added a new value in Java for Enum but not in the database yet. And when I run my junit test by creating a mock dataset I get the following exception java.lang.IllegalArgumentException: Unknown ordinal value for enum class PromotionTypeEnum
does your table's row's cell have a legal value for the enum?

So i need the following values: Values
I want to get them and save them in a variable for example. Do you have any suggestions for me ?
I want to get them to save the last position of an element. :)
if you have access to your element you can use a reference to it with a ViewChild for example https://angular.io/api/core/ViewChild and then you can use
myElementRef.style.transform
This will only give you a string containing the value of the property transform. If you want to access the values you would have to parse the string.

Can any one help me with the Java equivalent of this?
wordCountRDD.saveAsNewAPIHadoopFile(outputFile,classOf[Text],classOf[IntWritable],classOf[TextOutputFormat[Text,IntWritable]])
I tried below : but it give me error at TextOutputFormat<>(Text,IntWritable) ..
wordCountRDD.saveAsNewAPIHadoopFile(
output,
Text.class,
IntWritable.class,
TextOutputFormat<>(Text,IntWritable)
context.hadoopConfiguration());
Here:
TextOutputFormat<>(Text,IntWritable)
You have to pass the class instead:
TextOutputFormat.class
But note: the java type system doesn't allow you to express something like. TextOutputFormat<Text,IntWritable>.class! See here for why that is.
From that point of view, TextOutputFormat.class seems to be your only option.

My sqlserver table has a column designed as a BIT datatype. It has values 1 and 0s
Then in my Java code, I do
result = new ArrayList
result.add( (Boolean)(rs.getBoolean("columnName")));
Then when I read the value from the list - it shows as Long.
According to everything I find, it says hat a BIT datatype is supposed to map to boolean.
Why does it come as Long?
What can be done to fix this?
You can call getBoolean directly and let it take care of all the casting/coverting:
result.add(rs.getBoolean("columnName"));
