Hemanth Yamijala commented on MAPREDUCE-1140:
---------------------------------------------
I looked at the Yahoo! hadoop 0.20 patch, and have the same comment with
respect to throwing the exception in DistributedCache.getLocalCache. Other than
that, it looks fine.
Regarding the tests, I spoke offline to Amarsri to understand the scenario
executed by Karthikeyan in the comment above. It was not very clear why file1
was being added twice. Some more details on configuration - that it was run on
a single node, max failures was set to 1 should be documented for better
understanding.
In order to match the regressions tests in trunk, I would suggest we also have
in Job 2 a file, say file5, which we should verify is not even localized
(because file3 fails localization). Then we can include file 5 in Job 3 and
make sure localization happens successfully.
