[jira] [Created] (HDFS-7244) Reduce Namenode memory using Flyweight pattern
Amir Langer created HDFS-7244: - Summary: Reduce Namenode memory using Flyweight pattern Key: HDFS-7244 URL: https://issues.apache.org/jira/browse/HDFS-7244 Project: Hadoop HDFS Issue Type: Improvement Components: namenode Reporter: Amir Langer Using the flyweight pattern can dramatically reduce memory usage in the Namenode. The pattern also abstracts the actual storage type and allows the decision of whether it is off-heap or not and what is the serialisation mechanism to be configured per deployment. The idea is to move all BlockInfo data (as a first step) to this storage using the Flyweight pattern. The cost to doing it will be in higher latency when accessing/modifying a block. The idea is that this will be offset with a reduction in memory and in the case of off-heap, a dramatic reduction in memory (effectively, memory used for BlockInfo would reduce to a very small constant value). This reduction will also have an huge impact on the latency as GC pauses will be reduced considerably and may even end up with better latency results than the original code. I wrote a stand-alone project as a proof of concept, to show the pattern, the data structure we can use and what will be the performance costs of this approach. see [Slab|https://github.com/langera/slab] and [Slab performance results|https://github.com/langera/slab/wiki/Performance-Results]. Slab abstracts the storage, gives several storage implementations and implements the flyweight pattern for the application (Namenode in our case). The stages to incorporate Slab into the Namenode is outlined in the sub-tasks JIRAs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

[jira] [Commented] (HDFS-7244) Reduce Namenode memory using Flyweight pattern

The pattern also abstracts the actual storage type and allows the > decision of whether it is off-heap or not and what is the serialisation > mechanism to be configured per deployment. > The idea is to move all BlockInfo data (as a first step) to this storage > using the Flyweight pattern. The cost to doing it will be in higher latency > when accessing/modifying a block. The idea is that this will be offset with a > reduction in memory and in the case of off-heap, a dramatic reduction in > memory (effectively, memory used for BlockInfo would reduce to a very small > constant value). > This reduction will also have an huge impact on the latency as GC pauses will > be reduced considerably and may even end up with better latency results than > the original code. > I wrote a stand-alone project as a proof of concept, to show the pattern, the > data structure we can use and what will be the performance costs of this > approach. > see [Slab|https://github.com/langera/slab] > and [Slab performance > results|https://github.com/langera/slab/wiki/Performance-Results]. > Slab abstracts the storage, gives several storage implementations and > implements the flyweight pattern for the application (Namenode in our case). > The stages to incorporate Slab into the Namenode is outlined in the sub-tasks > JIRAs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

Yongjun Zhang commented on HDFS-7235:
-
HI [~cmccabe],
Thanks for the review and discussion yesterday. I was in a rush to leave when I
put the previous comment with patch yesterday. Here is some more info to share:
* You said that external user might be deriving FsDatasetSpi interface, any
change to this interface might imply compatibility. This is a very good point.
So indeed it'd be nice if we can avoid changing FsDatasetSpi.
* If we use {{FsDatasetSpi#getLength}} method to check file existence, it's not
guaranteed that the replica state is FINALIZED. So it's not sufficient for the
fix here.
* Without changing FsDatasetSpi, we need to add similar logic as I did in rev
001 to DataNode.java. To check replica state in DataNode.java, I had to use the
deprecated method getReplica().
* Having this logic in DataNode.java is a bit concern to me, DataNode is
supposed to use FsDatasetSpi interface only, now we incorporate logic specific
to FsDatasetImpl in DataNode.java. If user derives FsDatasetSpi and write
their own version, the logic may not be the same as FsDatasetImpl. This might
cause potential problem. This is the point I was trying to make in last comment.
Would you please comment again?
Thanks.

> When to decommission a DN, the process hangs.
> What happens is, when NN chooses a replica as a source to replicate data on
> the to-be-decommissioned DN to other DNs, it favors choosing this DN
> to-be-decommissioned as the source of transfer (see BlockManager.java).
> However, because of the bad disk, the DN would detect the source block to be
> transfered as invalidBlock with the following logic in FsDatasetImpl.java:
> {code}
> /** Does the block exist and have the given state? */
> private boolean isValid(final ExtendedBlock b, final ReplicaState state) {
> final ReplicaInfo replicaInfo = volumeMap.get(b.getBlockPoolId(),
> b.getLocalBlock());
> return replicaInfo != null
> && replicaInfo.getState() == state
> && replicaInfo.getBlockFile().exists();
> }
> {code}
> The reason that this method returns false (detecting invalid block) is
> because the block file doesn't exist due to bad disk in this case.
> The key issue we found here is, after DN detects an invalid block for the
> above reason, it doesn't report the invalid block back to NN, thus NN doesn't
> know that the block is corrupted, and keeps sending the data transfer request
> to the same DN to be decommissioned, again and again. This caused an infinite
> loop, so the decommission process hangs.

I'm running a Hadoop 2.4.0 HDFS on my cluster and I'm getting this error quite
frequently. I'm writing to HDFS using Apache Flink.
Is there any workaround for this issue (HDFS configuration?) ?

Yongjun Zhang commented on HDFS-5194:
-
HI [~dep],
I was working on HDFS-7235 and found this jira, thanks for the great work you
have done here.
Some questions:
1. {{FsDatasetSpi}} currently has the {{@InterfaceAudience.Private}}
annotation, I assume it means we can still modify the FsDatasetSpi interface
and without breaking compatibility from external users' point of view, am I
correct?
2. For HDFS-7235, {{DataNode#transferBlock}} calls isValidBlock(), when it
returns false, DN reports the bad block to NN for some cases, and only send
error report back to NN for other cases. It failed to report bad block to NN
for the case described in HDFS-7235. I'm thinking about adding a new method
like {{needToReportInvalidBlock()}} to FsDatasetSpi, so when {{isValidBlock()}}
returns false, {{needToReportInvalidBlock()}} can be called to find out whether
DN need to report it as bad block. What do you think?
Thanks.

> When to decommission a DN, the process hangs.
> What happens is, when NN chooses a replica as a source to replicate data on
> the to-be-decommissioned DN to other DNs, it favors choosing this DN
> to-be-decommissioned as the source of transfer (see BlockManager.java).
> However, because of the bad disk, the DN would detect the source block to be
> transfered as invalidBlock with the following logic in FsDatasetImpl.java:
> {code}
> /** Does the block exist and have the given state? */
> private boolean isValid(final ExtendedBlock b, final ReplicaState state) {
> final ReplicaInfo replicaInfo = volumeMap.get(b.getBlockPoolId(),
> b.getLocalBlock());
> return replicaInfo != null
> && replicaInfo.getState() == state
> && replicaInfo.getBlockFile().exists();
> }
> {code}
> The reason that this method returns false (detecting invalid block) is
> because the block file doesn't exist due to bad disk in this case.
> The key issue we found here is, after DN detects an invalid block for the
> above reason, it doesn't report the invalid block back to NN, thus NN doesn't
> know that the block is corrupted, and keeps sending the data transfer request
> to the same DN to be decommissioned, again and again. This caused an infinite
> loop, so the decommission process hangs.

[jira] [Commented] (HDFS-7056) Snapshot support for truncate

Attachment: HDFS-7185.002.patch
Thanks Nicholas for the review! Update the patch to address the comments.
Because {{readProperties}} is called in multiple places, to bypass the
layoutversion mismatch while rolling rollback, the current patch passes in the
startup option and delay the layoutversion check while loading the fsimage.
I will do some more tests in my cluster later.

Jing Zhao updated HDFS-7185:
Attachment: HDFS-7185.003.patch
Update the patch: in {{updateStorageVersionForRollingUpgrade}} we should not
check the layout version number for rolling rollback case, because 1) we have
done this check before/while loading the fsimage, and 2) we have already used
the software's layout version number to set the storage directory's layout
version.
I have tested the patch in a 3-node cluster and looks like the rolling upgrade
(including rollback) works fine with the patch.

Jing Zhao updated HDFS-7185:
Attachment: HDFS-7185.004.patch
After an offline discussion with Nicholas, this 004 patch adds more restrict
check for rollingUpgrade rollback. Specifically, we check if the software's
layout version is the same with the fsimage's layout version if we're doing
rolling rollback.

Hi Ming, thanks for working on this. The patch looks pretty good. Some
comments:
- For heartbeatedSinceRegistration == false, let's check failed storage anyway,
i.e. no need to compare storageMap.size() > reports.length.
- The method removeBlocksOnDatanodeStorage(..) does not use anything in
DatanodeManager. We may move the code to
BlockManager.removeBlocksAssociatedTo(..).
- In HeartbeatManager.heartbeatCheck(), allAlive should be changed to allAlive
= dead == null && failedStorage == null.
- In DatanodeDescriptor.updateFailedStorage(..), check if a storage was already
failed. Log and update the state only if it was not already failed.
- HeartbeatManager.register(..) also calls
DatanodeDescriptor.updateHeartbeat(..). So setting
heartbeatedSinceRegistration = true in updateHeartbeat(..) is wrong. Need to
fix it.

Thanks Clarles for post the patch.
*1.*
{quote}
target.substring(0, target.lastIndexOf(Path.SEPARATOR_CHAR))
{quote}
could be empty string (if the parent if root), then will cause {{getEZForPath}}
failed.
*2.*
Don't invoke FSN#getEZForPath directly, it's a bit heavy, more importantly it
has own permission check which will cause some issues: For example, concat just
needs "write" permission for target, and "read, parent write" permission for
srcs. If we invoke {{getEZForPath}} on target or parent directly, it requires
"read" permission of the path.
Why not do a lite check of whether target is in an encryption zone in
{{concatInternal}}.

Attachment: HDFS-7208-2.patch
Thanks Nicholas for the review.
The latest patch addresses all your comments, except for the allAlive one. The
reason is the patch handles deadnode separately from the failedStorage.

Hello Yi, and all of the reviewers. What work remains for this patch, and can
I do anything to help? I had been +1 way back on patch version 3, but then
there were a few more rounds of feedback. Has all of the feedback been
addressed? This is great work, and I'd love to see it go into 2.6.0.

> I will give more detailed performance data in future. Absolutely it’s
> bottleneck and will vastly affect the end to end performance.
> AES(Advanced Encryption Standard) is recommended as a replacement of DES,
> it’s more secure; with AES-NI support, the throughput can reach nearly
> *2GB/s*, it won’t be the bottleneck any more, AES and CryptoCodec work is
> supported in HADOOP-10150, HADOOP-10603 and HADOOP-10693 (We may need to add
> a new mode support for AES).
> This JIRA will use AES with AES-NI support as encryption algorithm for
> DataTransferProtocol.
