Guanghao Zhang updated HBASE-21643:
-----------------------------------
Description:
The old method postMutationBeforeWAL is not accurate about what it do. It is
only called during increment and append. But the name is "Mutation"... And the
javadoc only said it will be called by increment...
{code:java}
* Called after a new cell has been created during an increment operation, but
before
* it is committed to the WAL or memstore.
{code}
We use this coprocessor in our use case. And need add some cells to apply to
WAL. So I introduced two new method postIncrementBeforeWAL and
postAppendBeforeWAL to instead of this.
