Description

following files under pig on spark project use 2 space indent:
org.apache.pig.backend.hadoop.executionengine.spark.converter.CollectedGroupConverter
org.apache.pig.backend.hadoop.executionengine.spark.JobMetricsListener
org.apache.pig.backend.hadoop.executionengine.spark.SparkLocalExecType

Now all the files under this project should use 4 space indent.

Besides SparkLauncher.java use tab to replace space. We don't use tab to replace space in all the files in this project so need change this file.
