Are you using a recent version of Drill?
It looks like there's a problem pushing down the IS NULL operator to
Oracle. We'll need to look into our Oracle dialect support but does the
following double negative serve as a workaround for getting the null
job_ids for you?
select a.* from ORACLE.`HR`.`JOBS` as a FULL JOIN ORACLE.`HR2`.`JOBS` as b ON
a.`JOB_ID` = b.`JOB_ID`
where a.`MAX_SALARY`>=6000 AND b.`MAX_SALARY` <=10000 andNOT b.`JOB_ID` IS
NOT NULL

Dear Team,
Can you please help on below scenario. How to over come this DATA_READ_ERROR?
select a.* from ORACLE.`HR`.`JOBS` as a FULL JOIN ORACLE.`HR2`.`JOBS` as b ON
a.`JOB_ID` = b.`JOB_ID`
where a.`MAX_SALARY`>=6000 AND b.`MAX_SALARY` <=10000 and b.`JOB_ID` IS NULL
throws error : Error: DATA_READ ERROR: The JDBC storage plugin failed while
trying setup the SQL query.
select a.* from ORACLE.`HR`.`JOBS` as a FULL JOIN ORACLE.`HR2`.`JOBS` as b ON
a.`JOB_ID` = b.`JOB_ID`
where a.`MAX_SALARY`>=6000 AND b.`MAX_SALARY` <=10000 and b.`JOB_ID` IS NOT
NULL
Working fine.
Thank you,
Arul
