Ashutosh Chauhan updated HIVE-8555:
-----------------------------------
    Description: 
{code}
SELECT key, value FROM src WHERE key = cast(86 as double);
86.0  val_86
{code}
With constant propagate off we get different and correct result.
{code}
set hive.optimize.constant.propagation=false;
SELECT key, value FROM src WHERE key=  cast(86 as double);
86  val_86
{code}

  was:
{code}
SELECT key, value FROM src WHERE key= cast(86 as double);
86.0  val_86
{code}
With constant propagate off we get different and correct result.
{code}
set hive.optimize.constant.propagation=false;
