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

             Summary: Add readRegionServerLastLogRollResult() variant which accepts server name parameter
                 Key: HBASE-16443
                 URL: https://issues.apache.org/jira/browse/HBASE-16443
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu
            Priority: Minor


Currently in LogRollBackupSubprocedure#RSRollLogTask#call, we have
{code} 
        HashMap<String, Long> serverTimestampMap = table.readRegionServerLastLogRollResult(backupRoot);
        String host = rss.getServerName().getHostname();
        int port = rss.getServerName().getPort();
        String server = host + ":" + port;
        Long sts = serverTimestampMap.get(host);
{code}
Last log roll result is retrieved for all the servers. Yet only the timestamp for relevant server is used.

This issue adds a variant of readRegionServerLastLogRollResult() which takes server name as second parameter.
The variant would be used in LogRollBackupSubprocedure#RSRollLogTask#call().
