Nicolas Spiegelberg commented on HBASE-3620:
--------------------------------------------
Let me see if I can hack up a 0.90 version. The main change was going from
server.getRegionsAssignment() to server.getOnlineRegions(). Note that the RS
assignment check is not truly parallel because
HConnection.getHRegionConnection() used a big lock. There is a subsequent JIRA
that will address this issue.
