[jira] Created: (HBASE-2457) RS gets stuck compacting region ad
infinitum
RS gets stuck compacting region ad infinitum
--------------------------------------------
Key: HBASE-2457
URL: https://issues.apache.org/jira/browse/HBASE-2457
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.4
Reporter: Todd Lipcon
Priority: Critical
Testing 0.20_pre_durability@934643, I ended up in a state where one region server got stuck compacting a single region over and over again forever. This was with a special config with very low flush threshold in order to stress test flush/compact code.

stack resolved HBASE-2457.
--------------------------
Fix Version/s: 0.20.4
0.20.5
Resolution: Fixed
Ok. I applied the bandaid so I can make an RC. On commit I changed it so we compact the last 3 files rather than the last 4 to be a little more conservative. I did not apply to TRUNK.
