Devaraj Das commented on HBASE-16115:
-------------------------------------
We saw a similar issue with Phoenix in the picture - what we observed was that
for user-triggered compactions, the compaction in the regionserver would run as
the user, and after the compaction, the regionserver would try to update a
system table in Phoenix. That'd fail with an authentication failure because of
the reason that there are no credentials to reach out to a remote server from
within the user's context. HBASE-14655 should handle that case.
> Missing security context in RegionObserver coprocessor when a compaction is
> triggered through the UI

> Key: HBASE-16115
> URL: https://issues.apache.org/jira/browse/HBASE-16115
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.20
> Reporter: Lars Hofhansl
>
> We ran into an interesting phenomenon which can easily render a cluster
> unusable.
> We loaded some tests data into a test table and forced a manual compaction
> through the UI. We have some compaction hooks implemented in a region
> observer, which writes back to another HBase table when the compaction
> finishes. We noticed that this coprocessor is not setup correctly, it seems
> the security context is missing.
> The interesting part is that this _only_ happens when the compaction is
> triggere through the UI. Automatic compactions (major or minor) or when
> triggered via the HBase shell (folling a kinit) work fine. Only the
> UI-triggered compactions cause this issues and lead to essentially
> neverending compactions, immovable regions, etc.
> Not sure what exactly the issue is, but I wanted to make sure I capture this.
