Project: Hive
Issue Type: Improvement
Components: Physical Optimizer
Affects Versions: 2.0.0
Reporter: Ashutosh Chauhan
Assignee: Ashutosh Chauhan
It seems like there are lot of usage of abstract Operator class where only
possibility is TableScanOp. This results in lot of uncertainty when that
parameter is passed in and is littered with instanceOf checks all over.
