Description

When using the minicluster with kerberos the various checks in SecureDataNodeStarter fail because the ports are not fixed.

Stacks like this one:

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)

There is already a setting to desactivate this type of check for testing, it could be used here as well....
