Jesus Camacho Rodriguez updated HIVE-21834:
-------------------------------------------
Description: Every time we create a filter, we try to simplify its
condition. However, we already have a rule that simplifies the expressions and
it is within the same loop as most of the rules that end up creating new
filters. Hence, it may seem we could be able to remove some of the calls to
simplify those conditions. (was: Every time we create a filter, we try to
