--------------------------------------

             Summary: Limit result array preallocation to avoid OOME with large scan caching
values
                 Key: HBASE-13269
                 URL: https://issues.apache.org/jira/browse/HBASE-13269
             Project: HBase
          Issue Type: Bug
            Reporter: Andrew Purtell
            Assignee: Andrew Purtell
             Fix For: 1.0.1, 0.98.12


Scan#setCaching(Integer.MAX_VALUE) will likely terminate the regionserver with an OOME due
to preallocation of the result array according to this parameter.  We should limit the preallocation
to some sane value. Definitely affects 0.98 (fix needed to HRegionServer) and 1.0.x (fix needed
to RsRPCServices), not sure about later versions.
