Pushed to trunk, branch-3.2, branch-3.1 and branch-3.0.
There are some conflicts for a branch-2 commit so I'm working on that.

[jira] [Commented] (HDFS-10477) Stop decommission a rack of DataNodes caused NameNode fail over to standby

Wei-Chiu Chuang commented on HDFS-10477:
Committing 007 soon.
[~arpitagarwal] I think that approach will require some study. Full block
reports is generated every few hours and our users may complain about excessive
replicas not going down.
On the other hand, there's some merits in delaying block invalidation. I
imagine a NN could be overwhelmed by the amount of IBRs after block
invalidation.

Arpit Agarwal commented on HDFS-10477:
--
Just a thought - it may be okay to skip this function altogether, and let the
block invalidations be handled by the full block reports. That will also
stagger the invalidation work.

Wei-Chiu Chuang commented on HDFS-10477:
The conflicts come from HDFS-13027 and HDFS-9390, but fairly simple.
Attached [^HDFS-10477.006.patch] to resolve conflicts and add extra check
that I mentioned above.

Wei-Chiu Chuang commented on HDFS-10477:
I took some time to review the patch.
bq. I don't recall if the BlockIterator is guaranteed to be consistent if the
FsNameSystem lock is released.
The lock is held when {{getBlockIterator()}} is called, so that's not a problem.
I think the thread safety concern should be instead about this line
{code}
for (DatanodeStorageInfo datanodeStorageInfo : srcNode.getStorageInfos()) {
{code}
Because getStorageInfos() returns an array copy of the internal storageMap,
this iteration is thread-safe. However, to prevent the rare case where a
storage goes bad and got pruned, care must be exercised to double check the
storage is valid. That is, make sure
{{srcNode.getStorageInfo[datanodeStorageInfo.getStorageID()]}} is not null
inside the for loop.
bq. It would have been better for the refreshNodes RPC to start the refresh on
a worker thread and complete the RPC call immediately. I assume we cannot
change the RPC behavior now for backwards compatibility.
This can be addressed by having a new refreshNodes() RPC, deprecate the old one
and update DFSAdmin to use the new RPC.
We should just update this patch to make it applicable to trunk, and commit it.
[~zhaoyunjiong] do you still like to work on this, or would you mind to let me
do it? Thanks.

Hi [~zhaoyunjiong], [~benoyantony],
I've been thinking about this some more. I think the change will be fine,
although hard-coding a 1ms sleep still feels kludgy.
Is the log snippet in the description complete? ~10 seconds to process 285258
blocks sounds extremely high. If this is easily reproducible perhaps profiling
will reveal inefficiencies in {{processExtraRedundancyBlocksOnReCommission}} or
its callees that can be fixed instead.

Benoy Antony commented on HDFS-10477:
-
Didn't see Arpit's previous comments. If the recommended approach is set to
dfs.namenode.fslock.fair to false, then it may be good to sleep for a
millisecond between lock release and re-acquisition.
The patch looks good to me , +1

Benoy Antony commented on HDFS-10477:
-
The patch looks good.
There is no need to sleep as the admin can control the lock fairness via
dfs.namenode.fslock.fair. The default value is true which means that the
earlier threads will acquire the lock.

-
It looks like test case is failing due to lock release, please check. Secondly,
when catching and swallowing {{InterruptedException}}, should we call
{{Thread.currentThread().interrupt()}} afterward, so that the interrupt status
isn't lost.

Arpit Agarwal commented on HDFS-10477:
--
I second [~kihwal]'s concern about releasing and reacquiring. We have been
recommending that _ dfs.namenode.fslock.fair_ be set to false as it gives
better overall RPC throughput.
I am also not sure about releasing the lock during iteration (in
_processExtraRedundancyBlocksOnReCommission_). I don't recall if the
BlockIterator is guaranteed to be consistent if the FsNameSystem lock is
released.
It would have been better for the refreshNodes RPC to start the refresh on a
worker thread and complete the RPC call immediately. I assume we cannot change
the RPC behavior now for backwards compatibility.

--
Those failed unit test is not related to this patch.
And there is no need to add new unit test for this patch since it's only add
steps to release the nameSystem writeLock and then acquire the lock again.

[~kihwal],
What's your opinion on the second patch? Any suggestions?
Should I combine those two patches? I mean, for the second patch if no Datanode
have more blocks than DFS_BLOCK_MISREPLICATION_PROCESSING_LIMIT and if there
are lots of DataNodes, then still might have trouble.

Kihwal Lee commented on HDFS-10477:
---
If the lock is simply released and re-acquired right away per datanode, the
maximum number of requests that will be processed between the 10 second locks
will be limited to something close to the number of RPC handlers, since that
will be the number of threads waiting for the lock. The lock fairness setting
will affect this, but the number will still be limited even if set to unfair
since the lock won't be completely unfair to avoid starvation. The HA
monitoring request from ZKFC will likely be served in one or two locking cycles
if it is being handled by a separate RPC server (thus mostly empty callqueue),
so the initial patch may indeed prevent a failover.
If the goal is to simply avoid a failover, then the patch may be sufficient.
But most RPC requests will timeout for many minutes. Is the HA monitoring
correctly assessing the service status then? IMO, in order to avoid a
failover and be able to maintain the service availability, we need to make it
finer grained or insert delay between locks.

Benoy Antony commented on HDFS-10477:
-
If its possible to release lock per storage, then that's better.
If not , I prefer the first version which does releases the lock per each
datanode without the additional processing.
The logs show that the each node is processed in around 10 seconds.
