---------------------------------------------
Summary: allow jobs to set a JAR that is in the distributed cached
Key: MAPREDUCE-4408
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4408
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: mrv1, mrv2
Affects Versions: 2.0.0-alpha, 1.0.3
Reporter: Alejandro Abdelnur
Assignee: Alejandro Abdelnur
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.
