Just the properties in here. Couple thoughts as you bring this up.
We probably want to have a ticket to make sure turning off Kerberos works
correctly in the future. The properties in the file (except nimbus.seeds) are
essentially set properties. We need our own client_jaas, and the
storm.thrift.transport has to be there for some reason and that's pretty much
constant on a secure cluster. That should also be made a property that flows
down from Storm.
nimbus.seeds is wrong and I need to carry that over from the actual Storm
property. And I even made sure it was in params_linux and forgot to use it.
