---------------------------------

             Summary: ClassCastException when filter pushdown is used with a bigint or float
column.
                 Key: DRILL-5086
                 URL: https://issues.apache.org/jira/browse/DRILL-5086
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.9.0
            Reporter: Robert Hou
            Assignee: Aman Sinha


This query results in a ClassCastException when filter pushdown is used.  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

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
