      Description

      The implementation of INFORMATION_SCHEMA.COLUMNS fails (aborts) when there is a column of an INTERVAL type:

      0: jdbc:drill:zk=local> USE dfs.tmp;
      ...
      0: jdbc:drill:zk=local> CREATE OR REPLACE VIEW TempView AS SELECT CAST( NULL AS INTERVAL HOUR ) FROM INFORMATION_SCHEMA.CATALOGS LIMIT 1 ;
      ----------------------+

      ok summary

      ----------------------+

      true View 'TempView' replaced successfully in 'dfs.tmp' schema

      ----------------------+
      1 row selected (0.062 seconds)
      0: jdbc:drill:zk=local> SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'TempView';
