Subject [GitHub] flink issue #2275: FLINK-3929 Support for Kerberos Authentication with Keyta...

Github user mxm commented on the issue:

    Thanks for testing this on an actual secure cluster. 
    Hmpf, only allowing to bind to privileged ports doesn't really improve security but we
have to deal with this limitation somehow. I was initially thinking we could just include
a custom version of the `MiniKDC` dependency in the Flink code. As you pointed out, this is
not possible because the problem lies in the `SecureDataNodeStarter` which returns the secure
resources. This class is part of `hadoop-hdfs`which we can't include a custom version because
it depends on the Hadoop version provided during build time.
    Once the patch is out, we can run this test in a special profile where we set the Hadoop
version which supports non-privileged ports. As of now, I don't see a feasible solution other
than skipping this test.
