Amar Kamat updated HADOOP-4288:
-------------------------------
Attachment: HADOOP-4288-v4.patch
Adding a patch that incorporates Hemanth's comments.
bq. The code adds a debug LOG statement that could print a null value of the
variable i in
+1.
bq. The test case does not seem to test that when job is removed, the
associated structures are correctly cleaned up
The internal structures are not visible in the test case. Since this issue is
about getting NPE when two jobs are submitted by the same user and one of them
finishes, I have written the test case just to check if {{assignTasks()}} works
when expected. If {{assignTasks}} works then I assume internal structures
should be fine.
