Project: Hive
Issue Type: Bug
Reporter: Thejas M Nair
Assignee: Thejas M Nair
Attachments: HIVE-5668.1.patch
The conversion of paths in MapWork.getPathToAliases is happening multiple times
in MapOperator.cleanUpInputFileChangedOp. Caching the results of conversion can
improve the performance of hive map tasks.
