Temporary space issue with Dimension Partitioning on EMR instances in Hadoop_index job

Challenge : We do see this error message when running Hadoop_index job on EMR instances with Dimension Partitioning

Error: org.apache.hadoop.mapreduce.task.reduce.Shuffle$ShuffleError: error in shuffle in InMemoryMerger - Thread to merge in-memory shuffled map-outputs

Root Cause : EMR instances might not have sufficient space or not adequately configured as Dimension Partitioning requires more temporary space for shuffle as it has to re-group.

Solution : Either upgrade EMR instances to higher configuration or run the job with lesser intervals like 1 hour or 6 hours instead of 1 day or 1 week.
