JobClient.runJob() should not kill the job on IOExceptions
----------------------------------------------------------
Key: HADOOP-3771
URL: https://issues.apache.org/jira/browse/HADOOP-3771
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Reporter: Amar Kamat
Currently the {{JobClient.runJob()}} submits a job to the job tracker and then
periodically asks the JT for the job's progress. On successive IOExceptions the
JobClient kills the job. This is not a desired behaviour since the JobClient is
issuing a kill-job command to the JT which is not reachable. This is a problem
for HADOOP-3245 since its highly possible that the JT can come up anytime and
then it makes no sense to kill the job.
