Thomas Friol commented on HADOOP-648:
-------------------------------------
In fatc it seems that in this method :
synchronized void ensureFreshStatus() throws IOException {
if (System.currentTimeMillis() - statustime > MAX_JOBPROFILE_AGE) {
this.status = jobSubmitClient.getJobStatus(profile.getJobId());
this.statustime = System.currentTimeMillis();
}
}
this.status is setted to null because jobSubmitClient.getJobStatus() returns
null
> JobClient waitForCompletion() method sometimes throws an NPE
