Review Comment:
I investigated before,
Similar ones are https://issues.apache.org/jira/browse/SPARK-20246.
At that time, it was because it was impossible to determine whether the
filter expression was deterministic for example `$"rand" > 5`, therefore, it
will incorrectly push down `$"rand" > 5`.
However, after the filter expression is replaced, it can be judged whether
it is a deterministic expression.
