------------------------------------

We should keep forward working on this jira. In flink project, we can not run some tests until
this issue fixed.

> When using the minicluster with kerberos the various checks in SecureDataNodeStarter
fail because the ports are not fixed.
> Stacks like this one:
> {quote}
> java.lang.RuntimeException: Unable to bind on specified streaming port in secure context.
Needed 0, got 49670
> 	at org.apache.hadoop.hdfs.server.datanode.SecureDataNodeStarter.getSecureResources(SecureDataNodeStarter.java:108)
> {quote}
> There is already a setting to desactivate this type of check for testing, it could be
used here as well....
