> Drill does not prune enough partitions for this query when filter pushdown is used with
metadata caching. The float column is being compared with a double value.
> {code}
> 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(*) from orders_parts_metadata
where float_id < 1100.0;
> {code}
> To reproduce the problem, put the attached files into a directory. Then 
> {code}
> create the metadata:
> refresh table metadata dfs.`path_to_directory`;
> {code}
> For example, if you put the files in /drill/testdata/filter/orders_parts_metadata, then
run this sql command
> {code}
> refresh table metadata dfs.`/drill/testdata/filter/orders_parts_metadata`;
> {code}
