Subject [jira] [Updated] (DRILL-5086) ClassCastException when filter pushdown is used with a bigint or float column.
Date Wed, 30 Nov 2016 20:09:58 GMT

     [ https://issues.apache.org/jira/browse/DRILL-5086?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Hou updated DRILL-5086:
------------------------------
    Description: 
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

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
