>             Project: Hive
>          Issue Type: Bug
>            Reporter: Dayakar M
>            Assignee: Dayakar M
>            Priority: Major

> Steps to reproduce:
> {quote}CREATE TABLE t0(c0 INT);
> CREATE TABLE t1(c0 DOUBLE);
> INSERT INTO t0 VALUES(0);
> INSERT INTO t1 VALUES('-0');
> SELECT * FROM t0, t1 WHERE t0.c0 = t1.c0;
> {quote}
> *Expected Result:* 0.0 -0.0
> *Actual:* No Rows selected
> That the predicate should evaluate to TRUE can be verified with the following 
> statement:
> {quote}SELECT t0.c0 = t1.c0 FROM t0, t1; 
> -------
> _c0
> -------
> true
> -------
> {quote}
> Similar issue fixed earlier as a part of HIVE-11174  for where clause 
> condition, now join condition is having issue.
