Description
Recently we met too many replication WALs problem in our production cluster. We need the DumpReplicationQueues tool to analyze the replication queues info in zookeeper. So I backport HBASE-16450 to our branch based 0.98 and did some improvements for it.
1. Show the dead regionservers under replication/rs znode. When there are too many WALs under znode, it can't be atomic transferred to new rs znode. So the dead rs znode will be leaved on zookeeper.
2. Make a summary about all the queues that belong to peer has been deleted.
3. Aggregate all regionservers' size of replication queue. Now the regionserver report ReplicationLoad to master, but there were not a aggregate metrics for replication.
4. Show how many WALs which can not found on hdfs. But the reason (WAL Not Found) need more time to dig.
