> 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
