Luke Lu commented on HADOOP-8192:
---------------------------------
@Amir, 3 test failures have different root causes and require different patch
review cycles. E.g., TestCombineFileInputFormat failure is a result of relying
on undefined HashMap iteration order in the implementation of
CombineFileInputFormat; TestStreamingBadRecords, AFAICT, only fails on plinux
(you guys need to figure out the root cause for this); TestCapacityScheduler
failures is a bit more serious, as it expose a JLS compliance bug (that can
crash JobTracker) in the current code base as well as the HashMap order issue.
Combining all these together is confusing for the patch review process.

> Some tests fail with IBM's JDK. They are
