Harsh J created HIVE-8606:
-----------------------------
Summary: [hs2] Do not unnecessarily call setPermission on staging
directories
Key: HIVE-8606
URL: https://issues.apache.org/jira/browse/HIVE-8606
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Affects Versions: 0.13.1
Reporter: Harsh J
Assignee: Harsh J
Priority: Minor
HS2 has made setPermission mandatory within its CLIService#setupStagingDir
method as a result of HIVE-6602.
This causes HS2 to fail to start if the owner of the staging directory is not
the same user as it, even though the directory is already 777. This is because
only owners and superusers of a directory can change its permission, not group
or others.
Failure appears as:
{code}
Caused by: org.apache.hive.service.ServiceException: Error setting stage
directories
at org.apache.hive.service.cli.CLIService.start(CLIService.java:132)
at org.apache.hive.service.CompositeService.start(CompositeService.java:70)
... 8 more
Caused by: org.apache.hadoop.security.AccessControlException: Permission denied
{code}
We should only call the setPermission if it is unsatisfactory.
