> After removing the use of the master's system timestamp for meta updates in
> [HBASE-18328|https://issues.apache.org/jira/browse/HBASE-18328] and now that
> we pass the timestamps during region open/close in
> [HBASE-18395|https://issues.apache.org/jira/browse/HBASE-18395], we can also
> remove all legacy usages of masterSystemTime.
> This was initially introduced in
> [HBASE-13709|https://issues.apache.org/jira/browse/HBASE-13709] to send the
> master's current system time during an open region RPC to fix a case where
> certain meta table updates could be eclipsed in very rare circumstances.
