Limit maximum number of files to include in a major compaction
--------------------------------------------------------------
Key: HBASE-3050
URL: https://issues.apache.org/jira/browse/HBASE-3050
Project: HBase
Issue Type: New Feature
Reporter: Jonathan Gray
Assignee: Jonathan Gray
Priority: Minor
Fix For: 0.90.0
We had a situation where we had massively overrun compactions during a load
tests.
A single store ended up with something like 200 store files. This table also
had large values, like 1MB+. A major compaction came in for the region and we
OOME'd.
It would be useful to have a maximum number of files to include during a major
compaction as a just-in-case measure if we do manage to get this many files in
there. Can make it so 0 means infinite so there will be no change in default
behavior.
