Konstantin Shvachko commented on HDFS-2452:
-------------------------------------------
Can you mock datanode.getXceiverCount() to throw OutOfMemoryError on the second
call. That way the error will come from DataXceiver.run(). Also forgot to
mention last time you do not need to sleep(30sec) in the test. Checking alive
once should be fine.
A javaDoc for the test description would be good to have.
Please don't do Patch Available for 0.22 pathces. This only triggers Jenkins
build failures. We will have to run test and test-patch locally anyway before
committing.
