>                 Key: HIVE-8907
>                 URL: https://issues.apache.org/jira/browse/HIVE-8907
>             Project: Hive
>          Issue Type: Improvement
>          Components: Logical Optimizer
>    Affects Versions: 0.14.0
>            Reporter: Ashutosh Chauhan

> e.g,
> {code}
> create table partition_test_partitioned(key string, value string) partitioned by (dt
string)
>  explain select * from partition_test_partitioned where cast(dt as double) >=100.0
and cast(dt as double) <= 102.0
> {code}
> For queries like above, although {{PartitionPruner}} is able to prune partitions correctly,
filter is still not optimized away by PCR, where it could.
