Subject [jira] [Created] (HBASE-13729) old hbase.regionserver.global.memstore.upperLimit is ignored if present
Date Wed, 20 May 2015 20:19:00 GMT
Esteban Gutierrez created HBASE-13729:

             Summary: old hbase.regionserver.global.memstore.upperLimit is ignored if present
                 Key: HBASE-13729
                 URL: https://issues.apache.org/jira/browse/HBASE-13729
             Project: HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 1.1.0, 1.0.1, 2.0.0
            Reporter: Esteban Gutierrez
            Assignee: Esteban Gutierrez
            Priority: Critical

If hbase.regionserver.global.memstore.upperLimit is present we should use it instead of hbase.regionserver.global.memstore.size
the current implementation of HeapMemorySizeUtil.getGlobalMemStorePercent() asumes that if
hbase.regionserver.global.memstore.size is not defined thenit should use the old configuration,
however it should be the other way around.

This has a large impact specially if doing a rolling upgrade of a cluster when the memstore
upper limit has been changed from the default.
