Zhijie Shen updated MAPREDUCE-4838:
-----------------------------------
Attachment: MAPREDUCE-4838_2.patch
Hi Sid,
Thanks for your comments. I've incorporated all your comments in the newest
patch. In addition, I've added the test cases. Please have a look at the newest
patch.
One thing which I should point out is that to make the test cases pass, I've
modified the modifiers of TaskAttemptImpl#dataLocalHosts and
TaskAttemptImpl#dataLocalRacks from "private final" to "protected". I did this
because I've reorganized the code, such that these two attributes will only be
evaluated in the constructor and once. This violates the mock and the spy
tricks in TestTaskAttempt#testHostResolveAttempt.
I'll create another issue to deal with exposing the additional info through UI.
Thanks,
Zhijie
