Elliott Clark created HBASE-9422:
------------------------------------
Summary: AsyncProcess and HTable will submit the same mutation
twice if there is an error locating region.
Key: HBASE-9422
URL: https://issues.apache.org/jira/browse/HBASE-9422
Project: HBase
Issue Type: Bug
Components: Client
Reporter: Elliott Clark
Priority: Minor
HTable#backgroundFlushCommits calls AsyncProcess#submit
AsyncProcess#submit tries to get the region location but doesn't remove the
mutation from the write buffer. If it doesn't get the location the mutation is
added to the error list.
then HTable#backgroundFlushCommits takes all mutations from the error list and
adds them to the write buffer list.
This should result in two references to the same mutation being in the write
buffer list twice. It's not a big deal as two of the same mutation being
executed should be ideponent (unless the two puts are executed across ms
boundaries.)
