    Description

      After adding the timeout to TestUnderReplicatedBlocks in HDFS-4061 we can see the root cause of the failure is ReplicaAlreadyExistsException:

      org.apache.hadoop.hdfs.server.datanode.ReplicaAlreadyExistsException: Block BP-1541130889-172.29.121.238-1350435573411:blk_-3437032108997618258_1002 already exists in state FINALIZED and thus cannot be created.
