[jira] [Commented] (HIVE-19870) HCatalog dynamic partition query
can fail, if the table path is managed by Sentry
[ https://issues.apache.org/jira/browse/HIVE-19870?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16511181#comment-16511181 ]
Peter Vary commented on HIVE-19870:
-----------------------------------
After HIVE-16392, I think a good solution for master, and branch3 is to remove the applying of the permissions (See: HIVE-19870.2.patch). What do you think [~stakiar]?

> 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

> and

> 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
