Hi @JoshRosen , I was just looking into this.  With some local testing, I 
could confirm that this patch did lead to those failures, but that it is fixed 
by https://github.com/apache/spark/pull/9923 (in particular the handling of an 
empty stream in `TransportResponseHandler`)

2015-11-23 Thread JoshRosen
Github user JoshRosen commented on the pull request:

https://github.com/apache/spark/pull/9530#issuecomment-159187716
  
The following two tests have failed for the past three builds in the Hadoop 
2.4 Maven Jenkins job:

- org.apache.spark.deploy.yarn.YarnClusterSuite.run Spark in yarn-client 
mode
- org.apache.spark.deploy.yarn.YarnClusterSuite.user class path first in 
client mode

According to Jenkins, these failures first started in 
https://amplab.cs.berkeley.edu/jenkins/job/Spark-Master-Maven-with-YARN/HADOOP_PROFILE=hadoop-2.4,label=spark-test/4223/

Given the set of patches in that changeset, my hunch is that this might 
have somehow been caused by either #9853 or #9530 (this patch). Branch 1.6 only 
includes #9853 and seems to be passing these tests, so I therefore believe that 
this patch may be the culprit (since it's only present in master and not 1.6). 
@vanzin, could you help me look into this?

LGTM. But let's just merge this one to master since it's too risky to add a

> Maybe you can just submit more prs basing on previous ones

I don't know of any clean way of doing that in github; they'd end up 
including all the code in this PR, which is rather ugly / sub-optimal.

I can wait for the config change (I want to push it soon anyway), but I'm 
not super worried about conflicts. Those are generally not hard to resolve.

Alright I looked a bit closer at this. Since it is not mission critical and 
it is touching some mission critical part, I think it's best to not to merge 
this in 1.6. 

Let's merge this once 1.6 has an rc?

What's the problem with merging to master? Isn't that why we have

I have changes built on top of this that I'm waiting to send for review.

Do you mean bugs in this code? Or in 1.6? If in this code, master will 
eventually go through stabilization also, and at that point if there are bugs, 
they'll surface. Whether this code goes in now or later doesn't change much in 
that regard.

There are still some network related code that's going into 1.6 (one is the 
config naming thing). I'm concerned they might conflict. Maybe you can just 
submit more prs basing on previous ones for reviewing?

We should be pretty close to cutting a rc anyway.
