Re: ERROR 2999: Unexpected internal error. null
If I were debugging this (note, I know nothing about cassandra), I would
put a flag in my ide on cassandra storage and see what is going on in
there, and why it is erroring out. Then I would follow that backwards into
whatever in Pig was generating that issue. That's pretty vague but can't
really say much else unless I knew a ton about CassandraStorage.
