-----------------------------------------------------------
It is more likely that another process grabbed the port. In general it is not a
good idea to hard-code or reuse the same port number in unit tests. We had to
fix a lot of such test cases in the past. The jenkins slave can run multiple
jobs at the same time and also hdfs tests can run in parallel.
