[jira] [Commented] (HDFS-11187) Optimize disk access for last partial chunk checksum of Finalized replica
[ https://issues.apache.org/jira/browse/HDFS-11187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16360977#comment-16360977 ] Gabor Bota commented on HDFS-11187: --- [~jojochuang] thanks for the review! I'd like to reflect on your second comment because I think the first one is for rev001. In FsDatasetImpl#finalizeReplica there's a call on FsVolumeImpl#addFinalizedBlock() in line 1734 on your trunk commit. I moved the load checksum logic to the else branch, in FsDatasetImpl#finalizeReplica after the call is done to the unmodified FsVolumeImpl#addFinalizedBlock() for branch-2. I think this will solve the issue that you've pointed out.

> I tried to run the following command on a Hadoop 2.6.0 cluster with HA
> support
> $ hdfs dfsadmin -refreshNamenodes datanode-host:port
> to refresh name nodes on data nodes after I replaced one name node with a new
> one so that I don't need to restart the data nodes. However, I got the
> following error:
> refreshNamenodes: HA does not currently support adding a new standby to a
> running DN. Please do a rolling restart of DNs to reconfigure the list of NNs.
> I checked the 2.6.0 code and the error was thrown by the following code
> snippet, which led me to this JIRA.
> void refreshNNList(ArrayList addrs) throws IOException {
> Set oldAddrs = Sets.newHashSet();
> for (BPServiceActor actor : bpServices)
> { oldAddrs.add(actor.getNNSocketAddress()); }
> Set newAddrs = Sets.newHashSet(addrs);
> if (!Sets.symmetricDifference(oldAddrs, newAddrs).isEmpty())
> { // Keep things simple for now -- we can implement this at a later date.
> throw new IOException( "HA does not currently support adding a new standby to
> a running DN. " + "Please do a rolling restart of DNs to reconfigure the list
> of NNs."); }
> }
> Looks like this the refreshNameNodes command is an uncompleted feature.
> Unfortunately, the new name node on a replacement is critical for auto
> provisioning a hadoop cluster with HDFS HA support. Without this support, the
> HA feature could not really be used. I also observed that the new standby
> name node on the replacement instance could stuck in safe mode because no
> data nodes check in with it. Even with a rolling restart, it may take quite
> some time to restart all data nodes if we have a big cluster, for example,
> with 4000 data nodes, let alone restarting DN is way too intrusive and it is
> not a preferable operation in production. It also increases the chance for a
> double failure because the standby name node is not really ready for a
> failover in the case that the current active name node fails.

Íñigo Goiri commented on HDFS-13119:
* Haven't been able to go too deep but it seems like killing the mini cluster
messes with the other unit tests.
* I think we could also test {{renewLease()}} to see if it succeeds when just
one nameservice is down; in addition, we may want to put metrics for the number
of retries and check them in the unit test.
* One thing I was considering was being able to try at least once if we don't
have an NN ACTIVE; something like setting {{retryCount}} to he max value -1.
* I think {{DFS_ROUTER_CLIENT_THREADS_SIZE_DEFAULT}} in {{DFSConfigKeys}} fits
in one line.

[jira] [Created] (HDFS-13136) Avoid taking FSN lock while doing group member lookup for FSD permission check
Xiaoyu Yao created HDFS-13136: - Summary: Avoid taking FSN lock while doing group member lookup for FSD permission check Key: HDFS-13136 URL: https://issues.apache.org/jira/browse/HDFS-13136 Project: Hadoop HDFS Issue Type: Bug Components: namenode Reporter: Xiaoyu Yao Assignee: Xiaoyu Yao Namenode has FSN lock and FSD lock. Most of the namenode operations need to take FSN lock first and then FSD lock. The permission check is done via FSPermissionChecker at FSD layer assuming FSN lock is taken. The FSPermissionChecker constructor invokes callerUgi.getGroups() that can take seconds sometimes. There are external cache scheme such SSSD and internal cache scheme for group lookup. However, the delay could still occur during cache refresh, which causes severe FSN lock contentions and unresponsive namenode issues. Checking the current code, we found that getBlockLocations(..) did it right but some methods such as getFileInfo(..), getContentSummary(..) did it wrong. This ticket is open to ensure the group lookup for permission checker is outside the FSN lock. -- This message was sent by Atlassian JIRA (v7.6.3#76005) - To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org

I'm uncertain about whether or not the fix is correct here: a lot of the code this is calling is completely new to me, so it's entirely possible there are side effects I haven't considered (like whether or not this causes data that should not be cleaned up because it's needed for the s0 snapshot to get deleted). > Lease not deleted when deleting INodeReference > -- > > Key: HDFS-13135 > URL: https://issues.apache.org/jira/browse/HDFS-13135 > Project: Hadoop HDFS > Issue Type: Bug >Reporter: Sean Mackrory >Assignee: Sean Mackrory >Priority: Major > Attachments: HDFS-13135.001.patch > > > In troubleshooting an occurrence of HDFS-13115, it seemed that there was > another underlying root cause that should also be addressed.

Thanks for reporting this and providing a patch Sean! Appreciate Kihwal's
comment too.
I tried to play with the code, but not able to let the test fail, with or
without the fix... Does it fail for you locally?
Looking at the test case, I think this is very similar to HDFS-12369. The unit
test of that one
({{TestDeleteRace#testDeleteAndLeaseRecoveryHardLimitSnapshot}}) was basically
the same: keep a file unclosed, then delete it. Only difference at that time is
(IIRC) a hard lease expiration was necessary to trigger the edits corruption.
Not sure if this is the bug fix Kihwal was mentioning hopefully not. But if
that is, and we want to do a different fix, I'm open to it. Suffice it to say,
I should quote the famous line - I'm not a snapshot expert. :)

[jira] [Commented] (HDFS-11187) Optimize disk access for last partial chunk checksum of Finalized replica

Thanks [~gabor.bota] for revving and [~jojochuang] for review.
Mostly LGTM, just 1 thing looking at the patch:
Could you please handle append too? In the trunk patch,
{{loadLastPartialChunkChecksum}} in append is fixed too, by setting from the
finalized replica directly. We should fix the same in {{FsDatasetImpl#append}}
for branch-2.

> The patch at HDFS-11160 ensures BlockSender reads the correct version of

> However, the implementation is not optimal, because it must always read the

[jira] [Created] (HDFS-13138) webhdfs of federated namenode does not work properly
KWON BYUNGCHANG created HDFS-13138:
--
Summary: webhdfs of federated namenode does not work properly
Key: HDFS-13138
URL: https://issues.apache.org/jira/browse/HDFS-13138
Project: Hadoop HDFS
Issue Type: Bug
Components: webhdfs
Affects Versions: 3.0.0, 2.7.1
Reporter: KWON BYUNGCHANG
my cluster has multiple namenodes using HDFS Federation.
webhdfs that is not defaultFS does not work properly.
when I uploaded to non defaultFS namenode using webhdfs.
uploaded file was founded at defaultFS namenode.
I think root cause is that
clientNamenodeAddress of non defaultFS namenode is always fs.defaultFS.
[https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/NameNode.java#L462]
{code:java}
/**
* Set the namenode address that will be used by clients to access this
* namenode or name service. This needs to be called before the config
* is overriden.
*/
public void setClientNamenodeAddress(Configuration conf) {
String nnAddr = conf.get(FS_DEFAULT_NAME_KEY);
if (nnAddr == null) {
// default fs is not set.
clientNamenodeAddress = null;
return;
}
LOG.info("{} is {}", FS_DEFAULT_NAME_KEY, nnAddr);
URI nnUri = URI.create(nnAddr);
String nnHost = nnUri.getHost();
if (nnHost == null) {
clientNamenodeAddress = null;
return;
}
if (DFSUtilClient.getNameServiceIds(conf).contains(nnHost)) {
// host name is logical
clientNamenodeAddress = nnHost;
} else if (nnUri.getPort() > 0) {
// physical address with a valid port
clientNamenodeAddress = nnUri.getAuthority();
} else {
// the port is missing or 0. Figure out real bind address later.
clientNamenodeAddress = null;
return;
}
LOG.info("Clients are to use {} to access"
+ " this namenode/service.", clientNamenodeAddress );
}
{code}
so webhdfs is redirected to datanode having wrong namenoderpcaddress parameter
finally file was located namenode of fs,defaultFS
workaround is
configure fs.defaultFS of each namenode to its own nameservice.
e.g.
hdfs://ns1 has fs.defaultFS=hdfs://ns1
hdfs://ns2 has fs.defaultFS=hdfs://ns2

Worked on the test based on [~pifta]'s original.
I think one thing that worths clarifying with Istvan is that, in the test the
UGI is just the setting up the client, for doing an NN RPC. So if I understand
correctly, what you observed from tests are all RPC behavior. The bug here is
after the client authenticates with NN, when the NN is doing its part to get
the edits see below
After some debugging, it seems this needs extra efforts to make a real test
that lets NN read the edits via {{EditLogFileInputStream$URLLog}}. Currently
{{DFSInotifyEventInputStream#poll}} would end up making the NN go the
{{EditLogFileInputStream$FileLog}}, hence not triggering the authentication
path reported. On the other hand, we can really unit test the stream, since we
do need the context of a NN RPC, and the context of NN loginuser. Will continue
working on this when I can find cycles

Does the fix itself make sense to you?
