[jira] Created: (HBASE-917) filesystem intensive operations such as
compaction should be load aware
filesystem intensive operations such as compaction should be load aware
-----------------------------------------------------------------------
Key: HBASE-917
URL: https://issues.apache.org/jira/browse/HBASE-917
Project: Hadoop HBase
Issue Type: Improvement
Components: regionserver
Reporter: Andrew Purtell
If the underlying filesystem is already severely stressed, running intensive operations such as compaction is asking for trouble. Ideally, such actions should be deferred until load is observed to lessen.

[jira] Commented: (HBASE-917) filesystem intensive operations such
as compaction should be load aware

Billy Pearson commented on HBASE-917:
-------------------------------------
I see my compaction stop now during a long insert jobs that is loading the server vary heavy.
I thank it related to HBASE-616 but I do not get any messages from in the logs as we see from HBASE-616
Once insert load slows the next memcache flush starts a compaction.
