> WebHCat cannot fetch correct percentComplete for Hive jobs

> Key: HIVE-6521

> Project: Hive
> Issue Type: Bug
> Components: WebHCat

> WebHCat E2E test TestHive_7 failed because percentComplete wasn't returned as
> expected.
> {noformat}
> check_job_percent_complete failed. got percentComplete "map 0% reduce 0%",
> expected "map 100% reduce 100%"
> {noformat}
> So, there are two problems here.
> # The log parsing is broken for status of percentComplete. In the stderr of
> the job we see:
> {noformat}
> Launching Job 1 out of 1
> Number of reduce tasks is set to 0 since there's no reduce operator
> Starting Job = job_1393486488858_0691, Tracking URL =
> http://ambari-sec-1393480847-others-2-4.cs1cloud.internal:8088/proxy/application_1393486488858_0691/
> Kill Command = /usr/lib/hadoop/bin/hadoop job -kill job_1393486488858_0691

> The assumption in the code is that the line containing the percent status
> will end after "reduce = \d+%" but that fails with the above.
> # The last status from Hive job is "map = 100%, reduce = 0%" instead of
> expected "map = 100%, reduce = 100%".
