> For a query that contains certain types of disjunctive filter conditions such as 'dir0=x
OR dir1=y'  we get wrong result when metadata caching is used.  This is a regression due to
DRILL-4530.  
> Note that the filter involves OR of 2 different directory levels. For the normal case
of OR condition at the same level the problem does not occur. 
> Correct result (without metadata cache) 
> {noformat}
> 0: jdbc:drill:zk=local> select count(*) from dfs.`orders` where dir0=1994 or dir1='Q3'
;
> +---------+

> Wrong result (with metadata cache):
> {noformat}
> 0: jdbc:drill:zk=local> select count(*) from dfs.`orders` where dir0=1994 or dir1='Q3'
;
> +---------+
> | EXPR$0  |
