Anoop Sam John commented on HBASE-15600:
----------------------------------------
bq.acquiredRowLocks.add(getRowLock(mutation.getRow(), true));
If the other jira can committed 1st, we can change here to use
getRowLockInternal?
Also abt the inconsistent ops in doMiniBatch and mutateRows() u plan to raise a
Jira? We can handle that there.
> Add provision for adding mutations to memstore or able to write to same
> region in batchMutate coprocessor hooks

> As part of PHOENIX-1734 we need to write the index updates to same region
> from coprocessors but writing from batchMutate API is not allowed because of
> mvcc.
> Raised PHOENIX-2742 to discuss any alternative way to write to the same
> region directly or not but not having any proper solution there.
> Currently we have provision to write wal edits from coprocessors. We can set
> wal edits in MiniBatchOperationInProgress.
> {noformat}
> /**
> * Sets the walEdit for the operation(Mutation) at the specified position.
> * @param index
> * @param walEdit
> */
> public void setWalEdit(int index, WALEdit walEdit) {
> this.walEditsFromCoprocessors[getAbsoluteIndex(index)] = walEdit;
> }
> {noformat}
> Similarly we can allow to write mutations from coprocessors to memstore as
> well. Or else we should provide the batch mutation API allow write in batch
> mutate coprocessors.
