Subject Re: Cannot run Storm WordCountLocal
Date Wed, 07 Oct 2015 23:24:50 GMT
The mini cluster is started with not enough slots. I would guess that it is
luck that the IT case works because the test environment probably uses a
simple default of 4 slots or so for the mini cluster.

The LocalEnvironment in the DataSet API actually makes a pass over the
operators to see how many operators are executed and how they share the
slots, to compute how many slots are needed when the mini cluster is
started. I assume you need something similar here.
