Allow printing of TaskEvents for a Job from command line
--------------------------------------------------------
Key: HADOOP-925
URL: https://issues.apache.org/jira/browse/HADOOP-925
Project: Hadoop
Issue Type: Improvement
Components: mapred
Reporter: Devaraj Das
Priority: Minor
It might make sense to have these commands:
bin/hadoop job -numEvents <job_id> : this will print the number of events that
the job generated so far
bin/hadoop job <fromEvent> <maxEvents> <job_id> : this will print the events in
the range {fromEvent, fromEvent + maxEvents} for the given job id (only the
contents of the event objects, not the actual logs). For example, it might
print
event# 100, Map/Reduce, Success, http://foo.com:port/, taskId
bin/hadoop job <fromEvent> <maxEvents> <full> <job_id> : This will print the
contents of the logs (like what the JobClient does today)
