Our latest changes to set the closing flag seemed to have fixed the latest
split issues that we have been seeing. I also have not heard of any new
problems related to this bug so I’ll go ahead and mark it as resolved.
The closing flag change was checked into the stable 1.0.1 branch on Feb17 and
into mainline on Feb14 so it is in the released code.
Changed in trafodion:
status: In Progress → Fix Released
> LP Bug: 1274651 - Getting TM error 97 when our tables split or get moved.
> -------------------------------------------------------------------------
>
> 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.
