> failure was caused by a change in behavior for {{hbase.rowlock.wait.duration}} in HBASE-17210 (so 1.4.0+, 2.0.0+). Prior to that change setting the config <= 0 meant that row locks would succeed only if they were immediately available. After the change we fail the lock attempt without checking the lock at all.
> workaround: set {{hbase.rowlock.wait.duration}} to a small positive number, e.g. 1, if you want row locks to fail quickly.
