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.

Updated fix version. Hi [~xyao], now branch-2.7.3 is cut, so if you want to
include this in 2.7.3, you need to cherry-pick this to branch-2.7.3 as well.

[jira] [Created] (HDFS-10531) Add EC policy and storage policy related usage summarization function to dfs du command
GAO Rui created HDFS-10531:

Summary: Add EC policy and storage policy related usage
summarization function to dfs du command
Key: HDFS-10531
URL: https://issues.apache.org/jira/browse/HDFS-10531
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: GAO Rui
Currently du command output:
{code}
[ ~]$ hdfs dfs -du -h /home/rgao/
0 /home/rgao/.Trash
0 /home/rgao/.staging
100 M /home/rgao/ds
250 M /home/rgao/ds-2
200 M /home/rgao/noECBackup-ds
500 M /home/rgao/noECBackup-ds-2
{code}
For hdfs users and administrators, EC policy and storage policy related usage
summarization would be very helpful when managing storages of cluster. The
imitate output of du could be like the following.
{code}
[ ~]$ hdfs dfs -du -h -t( total, parameter to be added) /home/rgao
0 /home/rgao/.Trash
0 /home/rgao/.staging
[Archive] [EC:RS-DEFAULT-6-3-64k] 100 M /home/rgao/ds

[jira] [Updated] (HDFS-10529) Df reports incorrect usage when appending less than block size
[ https://issues.apache.org/jira/browse/HDFS-10529?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Pranav Prakash updated HDFS-10529: -- Attachment: HDFS-10529.000.patch Attached is a patch that attempts to fix this. Currently when any new block is created, first an RBW version is made and then it is finalized, passed to addFinalizedBlock() in BlockPoolSlice with the intended total block size. By looking at the difference between getOriginalBytesReserved() and originalBytesReserved() it is possible to see how many bytes were actually written, and the dfsUsage can be increased by this amount. The usage for the meta file can be added directly since the old meta is removed upon new block creation. > Df reports incorrect usage when appending less than block size > -- > > Key: HDFS-10529 > URL: https://issues.apache.org/jira/browse/HDFS-10529 > Project: Hadoop HDFS > Issue Type: Bug >Affects Versions: 2.7.2, 3.0.0-alpha1 >Reporter: Pranav Prakash >Priority: Minor > Labels: datanode, fs, hdfs > Attachments: HDFS-10529.000.patch > > > Steps to recreate issue: > 1.

[jira] [Created] (HDFS-10529) Df reports incorrect usage when appending less than block size
Pranav Prakash created HDFS-10529: - Summary: Df reports incorrect usage when appending less than block size Key: HDFS-10529 URL: https://issues.apache.org/jira/browse/HDFS-10529 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.7.2, 3.0.0-alpha1 Reporter: Pranav Prakash Priority: Minor Steps to recreate issue: 1. Create a 100MB file on HDFS cluster with 128MB blocksize and replication factor 3 2. Append 100MB to the file 3. Df reports around 900MB even though it should only be around 600MB. Looking at the blocks confirms that df is incorrect, as there exist only two blocks on each DN -- a 128MB block and a 72MB block. This issue seems to arise because BlockPoolSlice does not account for the delta increase in dfsUsage when an append happens to a partially-filled block, and instead naively adds the total block size. For instance, in the example scenario when when block is "filled" from 100 to 128MB, addFinalizedBlock() in BlockPoolSlice adds the size of the newly created block into the total instead of accounting for the difference/delta in block size between old and new. This has the effect of double-counting the old partially-filled block: it is counted once when it is first created (in the example scenario when the 100MB file is created) and again when it becomes part of the filled block (in the example scenario when the 128MB block is formed form the initial 100MB block). Thus the perceived size becomes 100MB + 128MB + 72 = 300 MB for each DN, or 900MB across the cluster. -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org

[jira] [Commented] (HDFS-9924) [umbrella] Asynchronous HDFS Access

Duo Zhang commented on HDFS-9924:
-
My concern is that, you can not tell people that hive is only compatible with
hadoop-2.8.x, right?
For example, we set hbase to be compatible with hadoop-2.4+, so usually we will
optimize for all hadoop-2.4+ versions if possible instead of using a new
feature only introduced in a newer version.
Here, a thread pool solution works for all hadoop-2.x versions. And it is not
that terrible to have 1MB stack size per thread... It is offheap, only
increases 1MB VSZ, not RSS, RSS will increase on demand. And you can set a
smaller stack size if you like to reduce the overhead.
For the implementation, what [~stack] said above is the experience we got from
our write-ahead-log implementation. And for the hive case here, yes, you have a
different pattern. But it is not a good idea to wait on Futures sequentially.
For example, you have request 0-99, and request 1 is blocked for a long time
and request 2-99 are all failed. With your solution, you will block on request
1 for a long time before resubmit the failed 2-99 request. This is a inherent
defect of lacking the support of callback. And a better solution is, sorry, but
again, using multiple threads. With a thread pool and {{CompletionService}},
you can (sometimes) get the failed request first.
Hope this could help. Thanks.

bq. In my experience, a bunch of rigging (threads) for polling, rather than
notification, is required when all you have is a Future to work with.
This is not true. There's no need to do threaded polling. You can look at
TestAsyncDFSRename#testConcurrentAsyncRename on how to simply use it, e.g.:
{code}
Map> retFutures = new HashMap>();
for (int i = 0; i < NUM_TESTS; i++) {
for (;;) {
try {
Future retFuture = adfs.rename(srcs[i], dsts[i],
Rename.OVERWRITE);
retFutures.put(i, retFuture);
break;
} catch (AsyncCallLimitExceededException e) {
/**
* reached limit of async calls, fetch results of finished async calls

waitForReturnValues(retFutures, start, end);

[jira] [Commented] (HDFS-10524) libhdfs++: Implement chmod and chown
[

]
James Clampffer commented on HDFS-10524:
Just a couple minor things, everything looks solid functionally.
Do we need to use std::tuple in FileSystemImpl::SetPermission and SetOwner to
make 1-tuples? They'll likely get inlined away but less templates generally
makes things easier to debug.
{code}
auto callstate = std::make_shared>>();
...
callstate->set_value(std::make_tuple(s));
...
auto returnstate = future.get();
Status stat = std::get<0>(returnstate);
{code}
It looks like there is some duplicate error checking code.
FileSystemImpl::SetPermissions will check the path and permission mask and then
call NameNodeOperations::SetPermission which does the same. Do we plan on
making the NameNodeOperations object accessable outside of FileSystem(Impl)?
If not it might be worth getting rid of the checks in one of them, or better
yet factoring out the checking code into a function and using that in both
places.

This simple usage solves our problem with making synchronous calls and wait for full roundtrip latency of each call. Threadpool has high overhead.

[jira] [Commented] (HDFS-10505) OIV's ReverseXML processor should support ACLs
[

Colin Patrick McCabe commented on HDFS-10505:
-
Thanks for this, [~surendrasingh]. It's good to see progress on supporting
ACLs here!
I am confused by the changes for setting {{latestStringId}} to 1, or
special-casing {{null}} in {{registerStringId}}. If we are going to do
"magical" things with special indexes in the string table, we need to document
it somewhere. Actually, though, I would prefer to simply handle it without the
magic. We know that a null entry for an ACL name simply means that the name
was an empty string. You can see that in {{AclEntry.java}}:
{code}
String name = split[index];
if (!name.isEmpty()) {
builder.setName(name);
}
{code}
In ReverseXML, we should simply translate these {{null}} ACL names back into
empty strings, and then the existing logic for handling the string table would
work, with no magic. We also need a test case which has null ACL names, so
that this code is being exercised.

Summary: libhdfs++: hdfsGetBlockLocations doesn't null terminate
ip address strings
Key: HDFS-10527
URL: https://issues.apache.org/jira/browse/HDFS-10527
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: James Clampffer
Assignee: James Clampffer
Code looks like this
{code}
strncpy(buf, ipaddr.c_str(),ipaddr.size());
{code}
But should be
{code}
strncpy(buf, ipaddr.c_str(),ipaddr.size()+1);
{code}
In order to make sure there is at least 1 null terminating byte. If we could
run the minidfscluster an another process and run valgrind on the libhdfs++
tests this would show up really quickly as a sequence of invalid reads when
that const char* was passed to std::string::string(const char*), strlen, or
strcpy.

There are multiple comments from both sides indicating that CompletableFuture is the ideal option for 3.x. [~arpiagariu] Please leave off concluding a discussion that is still ongoing (CF is not 'ideal' and is not a given). It doesn't help sir. bq. You mean just like we recently added 'avoid local nodes' because another downstream component wanted to try it? You misrepresent, again. HBase ran for years with a workaround while waiting on the behavior to show up in HDFS; i.e. the hbase project did not have an 'interest' in 'avoid local nodes'; they required this behavior of the filesystem and ran with a suboptimal hack until it showed up. In this case all we have is 'interest' and requests for technical justification go unanswered. bq. The Hive engineers think they can make it work for them and there was a compromise proposed to introduce the API as unstable. I'm interested in how Hive will do async w/ only a Future and in how this suboptimal API in particular will solve their issue (is it described anywhere?). In my experience, a bunch of rigging (threads) for polling, rather than notification, is required when all you have is a Future to work with. > [umbrella] Asynchronous HDFS Access > --- > > Key: HDFS-9924 > URL: https://issues.apache.org/jira/browse/HDFS-9924 > Project: Hadoop HDFS > Issue Type: New Feature > Components: fs >Reporter: Tsz Wo Nicholas Sze >Assignee: Xiaobing Zhou > Attachments: AsyncHdfs20160510.pdf > > > This is an umbrella JIRA for supporting Asynchronous HDFS Access. > Currently, all the API methods are blocking calls -- the caller is blocked > until the method returns.

Thanks, [~xiaochen]. Can you add a {{LOG.debug}} to the "if" statement that
talks about the block ID that is getting skipped?

[jira] [Updated] (HDFS-10525) Fix NPE in CacheReplicationMonitor#rescanCachedBlockMap
[ https://issues.apache.org/jira/browse/HDFS-10525?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Xiao Chen updated HDFS-10525: - Attachment: HDFS-10525.01.patch Patch 1 to fix this in the capacity check. The check added in HDFS-9549 was to handle a rare case where a block stuck in pending if the capacity is reached. I think there're 2 options on the fix: - ignore null blockInfo. We already have logic to remove the blocks that cannot be found on NN - remove immediately. I feel this may add a source of confusion since we have 1 more place to remove. To limit the change scope, patch 1 goes with option 1. > Fix NPE in CacheReplicationMonitor#rescanCachedBlockMap > --- > > Key: HDFS-10525 > URL: https://issues.apache.org/jira/browse/HDFS-10525 > Project: Hadoop HDFS > Issue Type: Bug > Components: caching >Affects Versions: 2.8.0 >Reporter: Xiao Chen >Assignee: Xiao Chen > Attachments: HDFS-10525.01.patch > > -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org

Jiayi Zhou commented on HDFS-10519:
---
Maybe I got something wrong, but isn't the MetaRecoveryContext already null at
the beginning?
In doTailEdits() from EditLogTailer, we have
streams = editLog.selectInputStreams(lastTxnId +
1, 0, null, inProgressTail);
Here, MetaRecoverContext is null. And in image.LoadEdits(), we have
public long
loadEdits(Iterable editStreams,
FSNamesystem target) throws IOException {
return loadEdits(editStreams, target, null,
null);
}
MetaRecoveryContext is also null.
Also, I don't know why toAtLeastTxId is always set to 0 in the implementation,
making the checkForGaps() method no use. If we set it to some other value, like
lastTxnId + 1, the multiple replay should be rejected.

> On busy clusters, users performing quota checks against a big directory

> we need finer grain control to avoid long read lock causing throughput drop.
> Even with unfair namesystem lock setting, a long read lock (10s of

How does it actually work? Can it replay the same edit log segment multiple

after it is finalized.
I thought it would blow up with {{MetaRecoveryContext}} being null.

[~xiaochen], thanks for letting me know. I've cherry-picked the fix to 2.6 and
2.7.

> On busy clusters, users performing quota checks against a big directory
> structure can affect the namenode performance. It has become a lot better
> after HDFS-4995, but as clusters get bigger and busier, it is apparent that
> we need finer grain control to avoid long read lock causing throughput drop.
> Even with unfair namesystem lock setting, a long read lock (10s of
> milliseconds) can starve many readers and especially writers. So the locking
> duration should be reduced, which can be done by imposing a lower
> count-per-iteration limit in the existing implementation. But HDFS-4995 came
> with a fixed amount of sleep between locks. This needs to be made
> configurable, so that {{getContentSummary()}} doesn't get exceedingly slow.

[jira] [Commented] (HDFS-10413) Implement asynchronous listStatus for DistributedFileSystem
[ https://issues.apache.org/jira/browse/HDFS-10413?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15329298#comment-15329298 ] Steve Loughran commented on HDFS-10413: --- Can I note that from the perspective of S3a, using listFiles(recursive=true) is significantly faster than using listStatus(). If code were encouraged to use that API rather than their own treewalk, then anything that works with object stores would see significant speedup. Also, listFiles and similar use the RemoteIterator. That code can be async, to the extent that the results can be arriving while the client is processing the previous results. The code I'm doing in HADOOP-13208 doesn't do that, but it does do windowed queries; you only get a window-full of files listed, filtered and made available at a time. This keeps memory consumption down. > Implement asynchronous listStatus for DistributedFileSystem > --- > > Key: HDFS-10413 > URL: https://issues.apache.org/jira/browse/HDFS-10413 > Project: Hadoop HDFS > Issue Type: Sub-task >Reporter: Xiaobing Zhou >Assignee: Xiaobing Zhou > > Per the > [comment|https://issues.apache.org/jira/browse/HDFS-9924?focusedCommentId=15285597&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15285597] > from [~mingma], this Jira tracks efforts of implementing async listStatus. -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
