Heng Chen commented on HBASE-14814:
-----------------------------------
I check some failed test case log, and NOT think it is caused by 'HDFS UI port
already in use'.
I post some failed test case stack trace here.

They are NN RPC port, DN RPC port, DN Xceiver port..... Of course, include
HDFS Web UI port.
They all try to bind localhost:0, it is very weird!
It seems all test cases failed to read configuration xml. wdyt? [~stack]
