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