> This is a continuation of HBASE-5494:
> Currently table-level write locks have been implemented using non-sequential ZNodes as
part of HBASE-5494 and committed to 89-fb branch. This issue is to track converting the table-level
locks to sequential ZNodes and supporting read-write locks, as to solve the issue of preventing
schema changes during region splits or merges.
