Haohui Mai commented on HDFS-6213:
----------------------------------
bq. Hmm, interesting. "0.0.0.0" is in DFSConfigKeys for
DFS_DATANODE_ADDRESS_DEFAULT, so this patch doesn't make it any worse.
This is two different issues. Though arguably it is usually okay to trigger UAC
when starting a DataNode, but it is unfavorable to trigger UAC during automated
testings. When fixing a test, I think it is better to make it robust (as this
is a simple change) instead of deferring the fix to another jira.

> if is in use (previous test?) the test fails.
