Review request for hive, Ashutosh Chauhan and Chris Nauroth.
Bugs: HIVE-14323
https://issues.apache.org/jira/browse/HIVE-14323
Repository: hive-git
Description
-------
HIVE-14323: Reduce number of FS permissions and redundant FS operations
1. Honor HIVE_WAREHOUSE_SUBDIR_INHERIT_PERMS when getting stage directory in
Context and in mkdir() in FileUtils
2. Reduce FS calls like exists()-->delete() to just delete().
3. Similar to #2 in Hive.replaceFiles()
4. Refactor Hive.trashFiles() so that it can make use of FileStatus information
if available (s3 FS lookups are expensive)
5. Refactor Hive.removeTempOrDuplicateFiles() so that it can make use of
FileStatus information if available (s3 FS lookups are expensive)
