This is the exception which was in nimbus log. (nimbus runs despite of the
exception)

Changing "StatsUtil.java" line 519 from "Integer port = (Integer)
value.get(1);" to "Integer port = ((Long) value.get(1)).intValue();" solved
that problem.
Then came another exception.

For now I have stopped testing storm-2.0.0-SNAPSHOT. Hope this helps others
though.
