> Some logs in ConstantPropagateProcFactory are not easy to understand, like query:
> select * from tbl where a = 'a1';
> showing some logs like this:
> optimizer.ConstantPropagateProcFactory: Filter org.apache.hadoop.hive.ql.udf.generic.GenericUDFOPEqual@78907a46 is identified as a value assignment, propagate it.
>
> Maybe It's better to log like this:
> optimizer.ConstantPropagateProcFactory: Filter (a = 'a1') is identified as a value assignment, propagate it.
