>                 URL: https://issues.apache.org/jira/browse/HBASE-16443
>             Project: HBase
>          Issue Type: Improvement
>            Reporter: Ted Yu
>            Priority: Minor
>              Labels: backup
>
> 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().
