Memstore.updateColumnValue passes wrong flag to heapSizeChange
--------------------------------------------------------------

                 Key: HBASE-3008
                 URL: https://issues.apache.org/jira/browse/HBASE-3008
             Project: HBase
          Issue Type: Bug
            Reporter: Jean-Daniel Cryans
            Assignee: Jean-Daniel Cryans
             Fix For: 0.90.0


Memstore.updateColumnValue passes the wrong flag to heapSizeChange, making it so that the
size keeps growing while the actual size is probably the same. For example, in our production
environment we see tables that only take ICVs doing flushes of a few KBs when it thinks there's
64MB in:

{noformat}
Started memstore flush for region somecountingtable,,1248719998664.121282795. Current region
memstore size 64.0
Added hdfs://borg9:9000/hbase/somecountingtable/121282795/counter/3564459650504019443, entries=905,
sequenceid=72504291507, 
memsize=183.3k, filesize=18.5k to somecountingtable,,1248719998664.121282795
{noformat}
