          Description

          TestReplicationPolicy: the log level checking is incorrect.

          TestBlocksScheduledCounter: HDFS-5222, which moved block schedule information from DatanodeDescriptor to DatanodeStorageInfo, is incorrect since a replica scheduled to a storage may eventually be written to another storage in the same datanode.

              +1 for the patch.

              I verified it fixes TestBlocksScheduledCounter. It looks like one test case is still failing in TestReplicationPolicy. We can fix it in a separate Jira.

              Just checked TestReplicationPolicy. It did not fail in my machine. Not sure why it still fails in your case.

              Both tests succeed after I synced the source tree.
