      Description

      If we have multiple cast of '' to varchar statements in a impala query which has a distinct like below, the query breaks for scenario when the cast to varchar limit in the SQL is lower than the previous cast.

       

      Query 1> Fails with " AnalysisException: null CAUSED BY: IllegalArgumentException: targetType=VARCHAR(100) type=VARCHAR(101)"

      SELECT DISTINCT CAST('' as VARCHAR(101)) as CL_COMMENTS,CAST('' as VARCHAR(100))  as CL_USER_ID FROM tablename limit 1

      Where as the below query succeeds

      Query 2> Success

       SELECT DISTINCT CAST('' as VARCHAR(100)) as CL_COMMENTS,CAST('' as VARCHAR(101))  as CL_USER_ID FROM  tablename limit 1

      Workaround
      SET ENABLE_EXPR_REWRITES=false;
