Matthew Liem updated HIVE-21705:
--------------------------------
Description:
Allow users to specify prefix for hiveoutput files. e.g
set hive.output.file.prefix=""
This would happen in the tmpPath -> finalPath rename.
Mapreduce has a similar feature with "mapreduce.output.basename" and the
proposed solution is to have a similar hive conf setting
"hive.output.file.prefix" that will append hive output file names
This would require we modify getFinalPath in the FileSinkOperator class and
pass in a prefix from a newly created HiveConf.ConfVars.OUTPUT_FILE_PREFIX
