Arpit Agarwal commented on HDFS-9530:

I take that back. I tested this again and verified the invalidate path is

+1 thanks [~brahmareddy].

Hi [~brahmareddy], the test case is still not exercising the changed code path. 
If you revert the change to FsDatasetImpl.java the test case still passes 
because closing the file finalizes the block.

[~arpitagarwal] thanks for catch.

bq.The failMirrorConnection hook looks unused. Also the DN should be updated to 
call the hook.

Yes, missed this from HDFS-9530-01 to HDFS-9530-02.. Now I uploaded..

[jira] [Commented] (HDFS-9530) huge Non-DFS Used in hadoop 2.6.2 & 2.7.1

Arpit Agarwal commented on HDFS-9530:

Thanks [~brahmareddy], the core change looks fine to me. The test case needs 
some more work. The {{failMirrorConnection}} hook looks unused. Also the DN 
should be updated to call the hook.

Using close will not exercise the changed code path since the block is 
finalized and not invalidated. We probably need to trigger the abandon block 
path in DataStreamer to trigger this invalidation as you correctly diagnosed 
earlier.
{quote}
If any of the datanode other than 1st DN is down for the first time pipeline 
creation,then Block will be abandoned and write will continue with new block.
In this case, the DN previous to bad link, will get IOE while connecting to 
mirror and in that case, reservedBytes will not be released for that DN.
{quote}

Thanks again for sticking with this difficult issue!

Brahma Reddy Battula commented on HDFS-9530:


Thanks to all.Uploaded patch..

Attached test case targeted current problem,  Tests available in 
{{TestSpaceReservation}} covers many other cases. 
IMO, If any more tests required, can be added as follow-up jira. Right?

I am thinking, this should go with 2.7.3 release.

[jira] [Commented] (HDFS-9530) huge Non-DFS Used in hadoop 2.6.2 & 2.7.1

Ravi Prakash commented on HDFS-9530:


This has been a long standing and complicated problem and your effort was 
laudable Arpit! It'd be great if we can tie this all down. Even if we can't 
write a comprehensive unit test to ensure all this byte accounting stays 
correct despite changes in the future, we should go ahead and fix the release 
of bytes on invalidate.

bq. Also agree with Vinayakumar B that releasing via invalidate is the safer 
option although it can lead to the reserved space hanging around longer.
Yes, I agree that it will hang around longer. But I think, that's fine as long 
as the block file is present on disk.

[jira] [Commented] (HDFS-9530) huge Non-DFS Used in hadoop 2.6.2 & 2.7.1

Arpit Agarwal commented on HDFS-9530:
-

I took a deeper look at the reservation code. It was painful to see my own lack 
of thoroughness.

I mostly agree with Brahma's analysis. Since reservation is done only for 
replicas created via BlockReceiver, there are a couple of potential culprits 
where the reservation could be leaked:
* Failure in {{DataXceiver#writeBlock}} after creating the BlockReceiver.
* BlockReceiver receives an unchecked exception after reserving.

Also agree with [~vinayrpet] that releasing via invalidate is the safer option 
although it can lead to the reserved space hanging around longer. 

Do we agree on the following summary of the contract for when space should be 
reserved and released?
# Space is reserved only when the on-disk block file is successfully created 
for an rbw/temporary replica. This is verifiably true in 
FsDatasetImpl#createTemporary and FsDatasetImpl#createRbw barring OOM when the 
ReplicaInPipeline/ReplicaBeingWritten is allocated.
# Space continues to be reserved as long as there is an rbw/temporary in the 
volumeMap.
# Space must be released either when the replica is finalized or it is 
invalidated. FsDatasetImpl#finalizeReplica handles the finalize case. Fixing 
invalidate would close the remaining gap.
## Space may be released earlier if a failure is detected earlier e.g. 
exception in BlockReceiver which we handle today.
## Space may also be released incrementally when some bytes are written to disk 
which is handled via ReplicaInPipeline#setBytesAcked.

Thanks again for the detailed analysis on this one Brahma, [~raviprak] and 
Vinay. Nice work.

[jira] [Commented] (HDFS-9530) huge Non-DFS Used in hadoop 2.6.2 & 2.7.1

Vinayakumar B commented on HDFS-9530:

Good analysis [~brahmareddy]. 
Your analysis makes sense.

IMO Releasing the remaining reserved bytes during invalidation is the better 
approach to deal with this issue.
As per my understanding and analysis, currently there is no other place where 
reserve/release is not consistent. But even if it comes in future, this change 
will avoid growing reserved space.

IMO, Even though there is workaround to overcome this, restarting datanodes 
everytime will be hard for clusters.
So this should be pushed before 2.8 comes out.

[jira] [Commented] (HDFS-9530) huge Non-DFS Used in hadoop 2.6.2 & 2.7.1

Ravi Prakash commented on HDFS-9530:


Perhaps we can postpone the question of whether RBW blocks which are recovered 
during a DN start / refresh of storages should have space reserved to another 
JIRA (since that is not causing the symptoms mentioned in this JIRA)

Thanks for the explanations Brahma! They are very helpful for me to understand 
the code.

Should we also reduce the reservation in {{FsDatasetImpl.removeVolumes}} after 
{{it.remove();}}? How about {{checkAndUpdate}}?

I'm trying to figure out why we missed releasing the space during 
{{invalidate}} as you found out. As you correctly point out, we reserve space 
only when a BlockReceiver is created.

-

Thanks for continuing to work on this [~brahmareddy] and your detailed 
analyses. Your reasoning sounds correct but I'd need more time to check this 
thoroughly.

I agree that this is complex so if I am also open to the option of removing the 
reservation if there may be a simpler alternative.

Brahma Reddy Battula commented on HDFS-9530:


bq. Do you think we should change reservedForReplicas when a datanode is 
started up and an older RBW replica is recovered? Specifically 
BlockPoolSlice.getVolumeMap addToReplicasMap(volumeMap, rbwDir, 
lazyWriteReplicaMap, false); 
Please Note that, "reservation" happens for Replicas which are instances of 
{{ReplicaInPipelineInterface}}. i.e. Only for ReplicaBeingWritten(RBW) and 
ReplicaInPipeline(TMP) blocks, both these will go through BlockReceiver. No 
reservation required during recovery (RWR/RUR) as no other data will be written 
to this, except recovery with DN restart case for upgrade in which expected 
block size is not tracked, no reservation happens.

bq. also it seems to me, since we aren't calling reserveSpaceForReplica in 
BlockReceiver but instead at a lower level, we will have to worry about calling 
releaseReservedSpace at that lower level.
Ideally thats correct. But reservation happens once, but release happens 
gradually for every packet. So ReplicaInPipeline instance will keep track of 
how much bytes released, and how much yet to release. Finally, during 
close/exception all remaining bytes will be released.

bq. Do you mean to imply that the places I found in this comment need not call 
reserveSpaceForReplica / releaseReservedSpace ?
Yes, IMO those places need not require to release any reserved space. As 
already mentioned above, only {{ReplicaInPipeline}} instances need to release, 
if reserved.

Ravi Prakash commented on HDFS-9530:


bq. 1. Reservation happens only when the block is being received using 
BlockReceiver. No other places reservation happens, so no need to release as 
well.
Thanks for reminding me Brahma! Do you think we should change 
{{reservedForReplicas}} when a datanode is started up and an older RBW replica 
is recovered? Specifically 
[BlockPoolSlice.getVolumeMap|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/fsdataset/impl/BlockPoolSlice.java#L361]
 {{addToReplicasMap(volumeMap, rbwDir, lazyWriteReplicaMap, false);}} . Also it 
seems to me, since we aren't calling {{reserveSpaceForReplica}} in 
BlockReceiver but instead at a lower level, we will have to worry about calling 
{{releaseReservedSpace}} at that lower level.
{quote}2. BlockReceiver constructor have a try-catch block where it will 
release all the bytes reserved, if there is any exceptions after reserving.
3. BlockReceiver#receiveBlock() have the try-catch block where it will release 
all the bytes reserved if there is any exceptions during the receiving 
process.{quote}
Could you please point me to the code where you see this happening? I mean 
specific instances of {{FsVolumeImpl.releaseReservedSpace}} being called with 
the stack trace.

bq. Only place left is in DataXceiver#writeBlock(), exception can happen after 
creation of BlockReceiver and before calling BlockReceiver#receiveBlock(), if 
failed to connect to Mirror nodes.
Do you mean to imply that the places I found in [this 
comment|https://issues.apache.org/jira/browse/HDFS-9530?focusedCommentId=15231164=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15231164]
 need not call {{reserveSpaceForReplica}} / {{releaseReservedSpace}} ?

[jira] [Commented] (HDFS-9530) huge Non-DFS Used in hadoop 2.6.2 & 2.7.1

Brahma Reddy Battula commented on HDFS-9530:


To Make it simple for analysis,

1. Reservation happens only when the block is being received using 
BlockReceiver. No other places reservation happens, so no need to release as 
well.
2. BlockReceiver constructor have a try-catch block where it will release all 
the bytes reserved, if there is any exceptions after reserving.
3. BlockReceiver#receiveBlock() have the try-catch block where it will release 
all the bytes reserved if there is any exceptions during the receiving process.
4. During successful receiving of packets, 
{{ReplicaInPipeline#setBytesAcked(..)}} will be called by {{PacketResponder}}
5. Once the block is completely received, {{FsDataSetImpl#finalizeReplica(..)} 
will release all the remaining reserved bytes.

Only place left is in {{DataXceiver#writeBlock()}}, exception can happen after 
creation of {{BlockReceiver}} and before calling 
{{BlockReceiver#receiveBlock()}}, if failed to connect to Mirror nodes.
Only in this case, bytes will not be released. But a ReplicaInfo instance will 
be already created in ReplicaMap.

Here, if the client re-creates the pipeline with same blockId, then same 
ReplicaInfo instance will be used, So no extra reservation happens. This can be 
verified using the same testcase as patch, but failing the pipeline for append, 
where abandonBlock will not be called, and pipeline will be recovered for same 
block.

But in case of fresh block creation, block will be abandoned and fresh block 
with new pipeline will be requested.
The old block created at Datanode will be eventually be deleted, BUT reserved 
space was never released. That's why you are not seeing many RBW blocks in RBW 
directory, but reserved space went on to accumulate > 1TB.

Though I have given two approaches, #1, releasing reserved bytes while deletion 
of ReplicaInPipeline instances, will cover all hidden cases, if any, as well.

Hope this helps.

Ravi Prakash commented on HDFS-9530:


Thanks for your attention and patch Brahma!
On a brief glance, your change to {{FsDatasetImpl}} seems to make sense. I'll 
dig in deeper.
I suspect {{releaseAllBytesReserved}} in DataXceiver (the approach you 
commented out in your patch) may remove more reservation than ideal because 
inside {{blockReceiver = new BlockReceiver(block, storageType, in,}} the code 
is a lot more nuanced. There are different contingencies based on whether its a 
new block / a block to be recovered / duplicate block etc. Please correct me if 
I am wrong.

Ravi Prakash commented on HDFS-9530:


FWIW, there is only a trivial amount of data in the RBW directory on the DN. So 
if we only released the reservation whenever we delete / move an RBW file, we 
would be fine.

Here's my analysis based on Hadoop-2.7.1 code. I'll see what makes sense in 
trunk shortly.
It seems to me that in addition to the places that we already do, we should be 
modifying the reserved space in these places too:
# {{BlockPoolSlice.resolveDuplicateReplicas}} (or perhaps {{deleteReplica}}) 
predicated on the replica being RBW
# {{FsDatasetImpl.convertTemporaryToRbw}} (after {{moveBlockFiles}})
# {{FsDatasetImpl.recoverRbw}} after {{truncateBlock}}
# {FsDatasetImpl.updateReplicaUnderRecovery}} after 
{{newReplicaInfo.setNumBytes(newlength);}}

I'd be interested in seeing if you all can find other places too. 

I wonder if the current implementation is too brittle and if there isn't a 
different place we can keep track of the required reservation? There may well 
not be. I'm surprised the feature itself was added without even a configuration 
to disable it.

Brahma Reddy Battula commented on HDFS-9530:


If any of the datanode other than 1st DN is down for the first time pipeline 
creation,then Block will be abandoned and write will continue with new block.
In this case, the DN previous to bad link, will get IOE while connecting to 
mirror and in that case, reservedBytes will not be released for that DN.
bq.There is some dead code in the patch.
I mentioned two approaches, one is commented,, Just for reference now.

now, will comment here later if I find it.

Ravi Prakash commented on HDFS-9530:


I took a heap dump of the Datanode process. I see the value of

[jira] [Commented] (HDFS-9530) huge Non-DFS Used in hadoop 2.6.2 & 2.7.1

Ravi Prakash commented on HDFS-9530:


Thanks for reporting Fei Hui. I can confirm that we are seeing this in our 
2.7.1 clusters too. I'll dig. It is *not* explained by HDFS-9038. e.g.
{code}
$ grep dfs.datanode.du.reserved -r .  -A 1
./hdfs-site.xml:dfs.datanode.du.reserved
./hdfs-site.xml-107374182400
{code}
We are seeing a deficit of way more than this 100Gb * number of disks.

Hi [~ferhui], did you execute df command when running the job? I suppose your 
hive job write a lot of temporary data in the local directories of the slave 
servers, and the temporary files are cleaned up after the job.

Fei Hui commented on HDFS-9530:

maybe it's different from HDFS-9038.

the example in description, dfs.datanode.du.reserved is 1G. dfs reports Non DFS 
Used: 40303602176 (37.54 GB), DFS Remaining: 29943965184 (27.89 GB) on 
worker-1. but df output is below on worker-1 
/dev/xvdc 20642428 2254196 17339656 12% /mnt/disk3 
/dev/xvdb 20642428 2721092 16872760 14% /mnt/disk4
/dev/xvdd 20642428 2274172 17319680 12% /mnt/disk2
/dev/xvde 20642428 2316260 17277592 12% /mnt/disk1

total 80G use 9.4G, free 68G. 

dfs report non dfs 37.54GB is inconsistent with df command

Chris Nauroth commented on HDFS-9530:
-

Additionally, Apache Hadoop 2.7.1 has a bug that configured 
{{dfs.datanode.du.reserved}} space gets counted towards non-DFS used.  The work 
of fixing this is tracked in HDFS-9038.

Xiaoyu Yao commented on HDFS-9530:
--

This looks like the symptom of HDFS-8072, where RBW reserved space is not 
released when Datanode BlockReceiver encounters an IOException. The space won't 
be releases until DN restart. 

The fix should be included in hadoop 2.6.2 and 2.7.1. Can you post the "hadoop 
version" command output?
