[jira] Created: (HBASE-3050) Limit maximum number of files to include in a major compaction

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.
