>                 Key: TRAFODION-174
>                 URL: https://issues.apache.org/jira/browse/TRAFODION-174
>             Project: Apache Trafodion
>          Issue Type: Bug
>          Components: dtm
>            Reporter: Guy Groulx
>            Assignee: John de Roo
>            Priority: Blocker
>             Fix For: 1.1 (pre-incubation)
>
>
> Testing with transaction enabled.
> Our system is using HortonWorks and is running HBASE 0.94 across 12 nodes.
> Our hbase max store size was 1GB.
> We noticed during loading of large tables, that we would get error 97 
> returned from the TM and that the batch of rows were not added.
> Turns out that our table was being split and that the TM is not handling this 
> at the moment.
> We also found out that after a split, the hbase balancer would move the new 
> region to another region server.   When this happened, we got more error 97.
> WORKAROUND:
> - We changed the MAX STORE SIZE to 100GB.
> - We changed the SPLIT POLICY to 
> org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy which 
> causes split to happen only once the max size if reached.   Default for HBASE 
> 0.94 and up is new POWERof2 policy which causes splits more often.
> - We turned off HBASE BALANCER via hbase shell.
