----------------------------------------
HI [~arpitagarwal],
I noticed that you are watching this one. I wonder if you could help reviewing
the latest patch of this JIRA and HDFS-6719? These are intermittent test
failures that I'm seeing among various test runs, and the patches are small.
Hopefully with them resolved, we can see clean runs more often.
For HADOOP-10872, since it's not easily reproduced, I didn't really figure out
why it failed to created "d1", because mkdirs is supposed to create the whole
path. However, I noticed that the test root dir is not created and cleaned for
each test in TestPathData, I fixed this and added a better debug message with
the patch, so we can see better why when it failed.
As noted in HDFS-6719, I'm seeing some interference between different tests for
us to watch out. But I think the fix I did for HDFS-6719 solve HDFS-6719 itself.
I may look at the TestIPC failure later when I have time, it's a long
outstanding failure across the board.
Thanks a lot.
