Chris Nauroth commented on HDFS-4491:
-------------------------------------
Thanks for the new patch, Andrey. It looks like surefire.forkNumber is going
to work nicely. I had another mostly successful test run on Windows with this
patch, except I still saw {{TestDecommission}} fail, this time trying to bind
to port 50020.
I reproduced this in isolation on Mac by running "nc -l 50020" in one shell,
"nc localhost 50020" in a second shell, and "mvn -Pparallel-tests test
-Dtest=TestDecommission" in a third shell. Somehow this test is not using
ephemeral ports for the data nodes.
