-------------------------------------
Summary: 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
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.
