--------------------------------------

Phabricator indicates that it has been committed to 0.89-fb. I'm working on a trunk port for this.

> 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.
