Robert Kanter commented on MAPREDUCE-4408:
------------------------------------------
I pulled the latest changes to trunk on my machine and those tests also fail
(without my patch). It looks like it must be one or more of these commits
that's causing the failures:
{code}HADOOP-4572. Can not access user logs - Jetty is not configured by
default to serve aliases/symlinks (ahmed via tucu)
Revert HDFS-3837. Fix DataNode.recoverBlock findbugs warning.
Ammend previous commit to remove TestFileCreationNamenodeRestart.
HDFS-3715. Fix TestFileCreation#testFileCreationNamenodeRestart. Contributed by
Andrew Whang{code}

> Key: MAPREDUCE-4408
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4408
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: mrv1, mrv2
> Affects Versions: 1.0.3, 2.0.0-alpha
> Reporter: Alejandro Abdelnur
> Assignee: Robert Kanter
> Attachments: MAPREDUCE-4408-branch-1.patch, MAPREDUCE-4408.patch

> Setting a job JAR with JobConf.setJar(String) and Job.setJar(String) assumes
> that the JAR is local to the client submitting the job, thus it triggers
> copying the JAR to HDFS and injecting it to the distributed cached.
> AFAIK, this is the only way to use uber JARs (JARs with JARs inside) in MR
> jobs.
> For jobs launched by Oozie, all JARs are already in HDFS. In order for Oozie
> to suport uber JARs (OOZIE-654) there should be a way for specifying as JAR a
> JAR that is already in HDFS.
