Robert Kanter updated MAPREDUCE-5215:
-------------------------------------
Attachment: MAPREDUCE-5215.patch
The new patch creates a JobClient only once getJobClient() is called. It
reuses the same cluster object from the Job to prevent any issues. Normally
the cluster is created lazily in connect() when submitting a job; if
getJobClient() is called, we have to connect() early for the JobClient to have
the cluster.
> mapreduce.Job is missing getJobClient() so its incompatible with MR1

> The method {{org.apache.hadoop.mapred.JobClient getJobClient()}} is in MR1's
> {{mapreduce.Job}} but doesn't exist in MR2's, which makes them incompatible.
> MR2's implementation of {{Job}} doesn't use a JobClient object, but we can
> create one and return it.
