> This query results in a ClassCastException when filter pushdown is used with
> metadata caching. The bigint column is being compared with an integer value.
> 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(\*) from
> orders_parts_metadata where bigint_id < 1100;
> Error: SYSTEM ERROR: ClassCastException: java.lang.Integer cannot be cast
> to java.lang.Long
> To reproduce the problem, put the attached files into a directory. Then
> create the metadata:
> refresh table metadata dfs.`path_to_directory`;
> For example, if you put the files in
> /drill/testdata/filter/orders_parts_metadata, then run this sql command
> refresh table metadata dfs.`/drill/testdata/filter/orders_parts_metadata`;
> A similar problem occurs when a float column is being compared with a double
> value.
> 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(\*) from
> orders_parts_metadata where float_id < 1100.0;
> Error: SYSTEM ERROR: ClassCastException
> Also when a timestamp column is being compared with a string.
> 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(\*) from
> orders_parts_metadata where timestamp_id < '2016-10-13';
> Error: SYSTEM ERROR: ClassCastException: java.lang.Integer cannot be cast
> to java.lang.Long
