Íñigo Goiri commented on HDFS-14974:
------------------------------------
Yes, this is only related to tests.
It also has issues if two tests using 8888 run in parallel.
In a regular environment, the cluster admin would just set the proper address
and port.
BTW, now that I'm seeing this:
{code}
conf.setInt(DFS_ROUTER_HANDLER_COUNT_KEY, 10);
{code}
This is a little overkill for a unit test; something like 2 or 4 threads should
be more than enough.
