> The test case is failing because all the required replicas are not moved in expected
storage. This is happened because of delay in datanode registration after cluster restart.
> Scenario :
> 1. Start cluster with 3 DataNodes.
> 2. Create file and set storage policy to WARM.
> 3. Restart the cluster.
> 4. Now Namenode and two DataNodes started first and  got registered with NameNode. (one
datanode  not yet registered)
> 5. SPS scheduled block movement based on available DataNodes (It will move one replica
in ARCHIVE based on policy).
> 6. Block movement also success and Xattr removed from the file because this condition
is true {{itemInfo.isAllBlockLocsAttemptedToSatisfy()}}.
> {code}
> if (itemInfo != null
>                 && !itemInfo.isAllBlockLocsAttemptedToSatisfy()) {
>               blockStorageMovementNeeded
>                   .add(storageMovementAttemptedResult.getTrackId());
>             ....................
>             ......................
>             } else {
>             ....................
>             ......................
>               this.sps.postBlkStorageMovementCleanup(
>                   storageMovementAttemptedResult.getTrackId());
>             }
> {code}
> 7. Now third DN registered with namenode and its reported one more DISK replica. Now
Namenode has two DISK and one ARCHIVE replica.
> In test case we have condition to check the number of DISK replica..
> {code} DFSTestUtil.waitExpectedStorageType(testFileName, StorageType.DISK, 1, timeout,
fs);{code}
> This condition never became true and test case will be timed out.
