---------------------------------
Summary: Inconsistent behavior for preBatchMutate in
doMiniBatchMutate and processRowsWithLocks
Key: HBASE-18703
URL: https://issues.apache.org/jira/browse/HBASE-18703
Project: HBase
Issue Type: Sub-task
Reporter: Duo Zhang
In doMiniBatchMutate, the preBatchMutate is called before building WAL, but in
processRowsWithLocks, we suggest the RowProcessor implementation to build WAL
in process method, which is ahead of preBatchMutate.
If a CP modifies the mutations, especially if it removes some cells from the
mutations, then the behavior of processRowsWithLocks is broken. The changes
applied to memstore and WAL will be different. And there is no way to remove
entries from a WALEdit through CP.
