----------------------------------
Hey [~amareshwari],
I have been trying to reproduce this but unable to. Can you tell me how can
I reproduce ?
I hive HiveDriver and JDBCDriver configured and I am deliberately timing out
JDBC estimation. The only possibiliity I can think of is - If HiveDriver
succeeds but the driver cost is still null but had to see why it should happen.
> NPE in estimate API if drivers timeout
