---------------------------------

             Summary: HCatalog dynamic partition query can fail, if the table 
path is managed by Sentry
                 Key: HIVE-19870
                 URL: https://issues.apache.org/jira/browse/HIVE-19870
             Project: Hive
          Issue Type: Bug
            Reporter: Peter Vary
            Assignee: Peter Vary


The central issue is that HCatalog is assuming it needs to handle the storage 
based authorization features. When a job completes, in HCatalog's file 
committing phase it tries to manually set the permissions for the table for 
authorization's sake, which makes it go against auto-authorization managment 
features provided by Sentry.

The offending code is specifically at 
[https://github.com/apache/hive/blob/master/hcatalog/core/src/main/java/org/apache/hive/hcatalog/mapreduce/FileOutputCommitterContainer.java#L373-L374]

and

[https://github.com/apache/hive/blob/master/hcatalog/core/src/main/java/org/apache/hive/hcatalog/mapreduce/FileOutputCommitterContainer.java#L380-L385]

and

[https://github.com/apache/hive/blob/master/hcatalog/core/src/main/java/org/apache/hive/hcatalog/mapreduce/FileOutputCommitterContainer.java#L952-L954]

where you can notice that _after_ it moves the files created by the job into 
their respective partition directories under the final table destination, it 
goes onto trying to perform chmod/chgrp operations which will fail out
