Hi,
I am trying to upgrade from 1.0.2 to 1.1.0 version of Storm.
And I see the below exception happening randomly on the Nimbus node.
When it happens, Nimbus is unable to accept any new topologies.
java.lang.NullPointerException: null

I have not been able to isolate what causes this exception.
Any help would be appreciated.
Thanks
