-------------------------------------
Summary: HiveInputFormat.processForWriteIds(Path dir, JobConf
conf, ValidTxnList validTxnList, List<Path> finalPaths)
Key: HIVE-17695
URL: https://issues.apache.org/jira/browse/HIVE-17695
Project: Hive
Issue Type: Sub-task
Components: Transactions
Reporter: Eugene Koifman
this has special handling for writes resulting from Union All query
In full Acid case at least, these subdirs get collapsed in favor of statementId
based dir names (delta_x_y_stmtId). It would be cleaner/simpler to make MM
follow the same logic. (full acid does it Hive.moveFiles() I think)
