In HBASE-8877 I'm proposing to change row locks to be reentrant and thread based rather than tracking lock ids. Part of that change would mean altering the RegionObserver coprocessor. Specifically, the methods preBatchMutate and postBatchMutate would have the parameter MiniBatchOperationInProgress<Pair<Mutation, Integer>> miniBatchOp become MiniBatchOperationInProgress<Mutation> miniBatchOp
Does anyone rely on lock ids for this coprocessor or object to the change? Is it safe to make this incompatible change for 0.96? Thanks, Andrew, for already chiming in on the issue. For more background, see that issue and discussion on HBASE-8806. Dave
