Summary: Fix
TestPersistentStoragePolicySatisfier#testWithCheckpoint failure
Key: HDFS-11965
URL: https://issues.apache.org/jira/browse/HDFS-11965
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Affects Versions: HDFS-10285
Reporter: Surendra Singh Lilhore
Assignee: Surendra Singh Lilhore
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.
