Dimitry,
Could you send me your filter expression on which the logical expression simplifier failed upon to help me debug the problem as this sits in the critical path of pig optimization?
I do not need your full query script and not even the exact filter expression but just the same expression structure with whatever field names you may put there. For instance if you have a filter as follows:
B = FILTER a BY (twitterField1 > 7 AND twitterField2 <3);
It will suffice for me to debug if you send me the following
B = FILTER a BY (foo1 > 7 AND foo2 <3);
In other word, it is the expression tree structure and operators that matters not the field names on the tree.
Thanks for help!
Yan

Please try "-t FilterLogicExpressionSimplifier" to turn it off.
In the meanwhile, could you send me your filter expression that you suspect the simplifier fails on?
Thanks,
Yan

I am getting mysterious errors that I think are due to the new optimizer in
pig 8.
How can I turn off individual rules (LogicalExpressionSimplifier in this
case)?
Thanks,
