Rakesh R commented on HDFS-10434:
-
I think I got the cause of the failure. It is wrongly finding out the datanode
to be corrupted from the block locations. Instead of finding out a datanode
which is used in the block locations it is simply getting a datanode from the
cluster, which may not be a datanode present in the block locations.
{code}
byte[] indices = lastBlock.getBlockIndices();
//corrupt the first block
DataNode toCorruptDn = cluster.getDataNodes().get(indices[0]);
{code}
For example, datanodes in the {{cluster.getDataNodes()}} array indexed like,
0->Dn1, 1->Dn2, 2->Dn3, 3->Dn4, 4->Dn5, 5->Dn6, 6->Dn7, 7->Dn8, 8->Dn9, 9->Dn10
Assume the datanodes which are part of block location is => Dn2, Dn3, Dn4,
Dn5, Dn6, Dn7, Dn8, Dn9, Dn10. Now, in the failed scenario, it is getting the
corrupted datanode as {{cluster.getDataNodes().get(0)}} which will be Dn1 and
corruption of this datanode will not result in ECWork and is failing the tests.
Ideally, the test should find a datanode from the block locations.
Basically there are two problems in this test case. First one was fixed as part
of this jira. For the second part, I think will raise another jira and fix it
as there is no relation between first and second.

And the test failure happens again at

Basically 10s is enough period to wait for the metrics updated. As [~yzhangal]
mentioned, is there a different issue? Thanks.

Hi Guys, thanks for the work here. I'm still seeing a failure at

wonder if it's a different issue than this one.

Thanks [~drankye] for the reviews. Attached new patch by renaming the variable
'counter' to 'retries'. Kindly review it again.

Thanks Rakesh for tracking this. The fix LGTM and +1. A minor is the *counter*
could be renamed to avoid a little confusing with metric counters.
{code}
+int counter = 20;
{code}
Will commit this shortly addressing the minor.

Thanks for [~rakeshr]'s detailed explanation. The situation described will
cause the test case fail and the patch can fix the problem. +1 for the patch.

Rakesh R commented on HDFS-10434:

Thanks [~libo-intel], we are updating the dn metrics at the finally block of
{{StripedReconstructor}} thread as shown below. The failure occurs because
{{StripedFileTestUtil.waitForReconstructionFinished()}} is waiting for the
block recovery but not waiting to finish executing the
StripedReconstructor#run() finally block section. Probably can try debugging
the failed test case {{TestDataNodeErasureCodingMetrics#testEcTasks}} by
putting a break point at the finally block and you can see
{{StripedFileTestUtil.waitForReconstructionFinished(file, fs, GROUPSIZE);}} is
coming out and failing the test case. To fix this, I added grace period so that
the thread will get a chance to execute the finally block to update the metrics
data.
StripedReconstructor.java
{code}
} finally {
datanode.decrementXmitsInProgress();
datanode.getMetrics().incrECReconstructionTasks();
stripedReader.close();
stripedWriter.close();
{code}

Thanks for [~rakeshr] finding the problem.
{{DFSTestUtil.waitForDatanodeState()}} and
{{StripedFileTestUtil.waitForReconstructionFinished()}} have make sure that the
reconstruction work is finished before checking the metrics. I am confused that
the two sentences not take effect. Does the failure never happen after
applying the patch(maybe run the test case more than 20 times)?
