bq.  A lot of the changes are essentially whitespace and indentation reformats, 
and those changes aren't necessary to fix the unit test behaviors. Do we really 
need those changes as part of this patch?

IMO, this is an *ideal* patch to fix the checkstyle issues with, especially 
since a) it's already a huge patch and b) it's patching code that isn't (last I 
checked) in branch-2.

I'll do a rebase etc etc and post an updated version later tonight if I get a 
chance.

 Summary: Shuffle audit logger should log size of shuffle transfer
 Key: MAPREDUCE-6958
 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6958
 Project: Hadoop Map/Reduce
  Issue Type: Improvement
Reporter: Jason Lowe
Assignee: Jason Lowe
Priority: Minor


The shuffle audit logger currently logs the job ID and reducer ID but nothing 
about the size of the requested transfer.  It calculates this as part of the 
HTTP response headers, so it would be trivial to log the response size.  This 
would be very valuable for debugging network traffic storms from the shuffle 
handler.

bq. Would folks be amenable if we commit a patch that basically 
fixes/modernizes the unit test code but doesn't actually enable parallel tests 
by default? 

Yes, that sounds great!  I'd hate for perfect to be the enemy of good here.  
There's some lingering issues with the parallel stuff, but in general I think 
there's great stuff here as far as making them better unit tests.

My apologies for not having had a chance to get back to this for a while, but 
I'd like to take a closer look at the patch tomorrow.  Just had a chance to 
glance at the patch so far, but one concern is that the patch is a lot bigger 
than it needs to be.  A lot of the changes are essentially whitespace and 
indentation reformats, and those changes aren't necessary to fix the unit test 
behaviors.  Do we really need those changes as part of this patch?

Given the whole unit test discussion in common-dev@ today, I had a thought on 
this issue.  Would folks be amenable if we commit a patch that basically 
fixes/modernizes the unit test code but doesn't actually enable parallel tests 
by default?  

My thinking is that would at least push us significantly forward and reduce the 
amount of code to have to churn through while working out the 5 or so 
unreliable tests.  I really don't want to lose any ground on this one again.

> After a connection failure from the reducer to the node manager, shuffles 
> started to hang with the following message:
> {code}
> org.apache.hadoop.mapreduce.task.reduce.Fetcher: fetcher#1 - MergeManager 
> returned status WAIT ...
> {code}
> There are two problems that leads to the hang.
> Problem 1.
> When a reducer has an issue connecting to the node manager, copyFromHost may 
> call putBackKnownMapOutput on the same task attempt multiple times.
> There are two call sites of putBackKnownMapOutput in copyFromHost since 
> MAPREDUCE-6303:
> 1. In the finally block of copyFromHost
> 2. In the catch block of openShuffleUrl.
> When openShuffleUrl fails to connect from the catch block in copyFromHost, it 
> returns null.
> By the time openShuffleUrl returns null, putBackKnownMapOutput would have 
> been called already for all remaining map outputs.
> However, the finally block calls putBackKnownMapOutput one more time on the 
> map outputs.
> Problem 2. Problem 1 causes a leak in MergeManager.
> The problem occurs when multiple fetchers get the same set of map attempt 
> outputs to fetch.
> Different fetchers reserves memory from MergeManager in Fetcher.copyMapOutput 
> for the same map outputs.
> When the fetch succeeds, only the first map output gets committed through 
> ShuffleSchedulerImpl.copySucceeded -> InMemoryMapOutput.commit, because 
> commit() is gated by !finishedMaps[mapIndex].
> This may lead to a condition where usedMemory > memoryLimit, while 
> commitMemory < mergeThreshold.
> This gets the MergeManager into a deadlock where a merge is never triggered 
> while MergeManager cannot reserve additional space for map outputs.

[jira] [Commented] (MAPREDUCE-6954) Disable erasure coding for files that are uploaded to the MR staging area

Almost there:
# I'm not a fan of double negatives in booleans - they make things hard to 
read.  I understand what you're doing here, relying on the default value to be 
true instead of setting it (that's a good idea btw), but instead of using 
{{!shouldBeDisabled}} let's use {{default}} instead.  That's much easier to 
follow.
#- In a similar vein, let's rename {{testErasureCodingNotDisabled}} to 
{{testErasureCodingDefault}}.
# There's some new checkstyle warnings about indenting and line length.

I like the idea! It would be nice to cleanup the checkstyle and javac warnings 
but otherwise +1 lgtm.

> This is the initial step of MAPREDUCE-6823, which proposes a factory behind 
> {{FileOutputFormat}} to create different committers for different 
> filesystems, if so configured..
> This patch simply adds the new abstract superclass of 
> {{FileOutputCommitter}}, {{PathOutputCommitter extends OutputCommitter}}. 
> This abstract class adds the {{getWorkPath()}} method as an abstract method, 
> with {{FIleOutputCommitter}} being the implementation..
> {{FileOutputFormat}} then relaxes its requirement of any committer returned 
> by {{getOutputCommitter()}}, so that instead of requiring a  
> {{FileOutputCommitter}} or subclass, it only needs a {{PathOutputCommitter}}, 
> using {{PathOutputCommitter.getWorkPath()}} to get the work path.
> What does that do?
> It allows people to implement subclasses of {{FileOutputFormat}} which can 
> provide their own committers *which don't need to inherit the complexity that 
> FileOutputCommitter has acquired over time*
> Currently anyone implementing a new committer (example: Netflix S3 committer) 
> needs to subclass {{FileOutputCommitter}}, which is too complex to understand 
> except under a debugger with co-recursive routines, lots of methods which 
> need to be overwritten to guarantee a safe subclass, and, because of its 
> critical role and known subclassing, something which isn't ever going to be 
> cleaned up.
> A new, lean, parent class which {{FileOutputFormat}} can handle allows people 
> to write new committers which don't have to worry about implementation 
> details of {{FileOutputCommitter}}, but instead how well they implement the 
> semantics of committing work.
> The full MAPREDUCE-6823 goes beyond this with a change to 
> {{FileOutputFormat}} for a factory for creating FS-specific 
> {{PathOutputCommitter}} instances. This patch doesn't include that, as that 
> is something which needs to be reviewed in the context of HADOOP-13786 and 
> ideally 1+ committer for another store, so people can say "this factory model 
> works".
> All I'm proposing here is: tune the committer class hierarchy in MRv2 so that 
> people can more easily implement committers, and when that factory is done, 
> for it to be switched to easily. And I'd like this in branch-3 from the 
> outset, so existing code which calls {{FileOutputFormat.getCommitter()}} to 
> get a {{FileOutputCommitter}} *just to call getWorkPath()* can move to the 
> new interface across all of Hadoop 3.

Allen Wittenauer commented on MAPREDUCE-6491:
-

a) DYLD_LIBRARY_PATH should be in the list
b)  As mentioned several times, this won't work if a job (e.g., streaming) 
calls the shell scripts with the default values.

[jira] [Updated] (MAPREDUCE-6491) Environment variable handling assumes values should be appended

2017-09-14 Thread Jason Lowe (JIRA)

 ]

Jason Lowe updated MAPREDUCE-6491:
--
Attachment: MAPREDUCE-6491.011.patch

I'd like to get this into 3.0.0-beta1 so the new behavior is part of the 
upcoming 3.x release.  As such I'm posting a minor update to the patch to 
address the javadoc and checkstyle issues.  The test failure appears to be 
unrelated and does not fail for me with the patch applied.

[~aw] is there anything else that needs to be done on this JIRA before it can 
go into trunk and branch-3.0?

> When processing environment variables for a container context the code 
> assumes that the value should be appended to any pre-existing value in the 
> environment.  This may be desired behavior for handling path-like environment 
> variables such as PATH, LD_LIBRARY_PATH, CLASSPATH, etc. but it is a 
> non-intuitive and harmful way to handle any variable that does not have 
> path-like semantics.
