Aaron T. Myers updated HDFS-2764:
---------------------------------
Attachment: HDFS-2764.patch
Here's a patch which addresses the issue.
The trouble was that a helper method used by both failing tests had a race
condition. In waitCheckpointDone, the test would just wait for the BN to get a
particular fsimage snapshot, and then assert that the NN also had that fsimage
snapshot, even though the BN might not have uploaded it back to the NN yet.
While I was in this test class I also took the liberty of updating it to a
JUnit 4-style test.
I guess it was failing consistently on my box because it's an SSD, and things
just move too damn fast.
