Ruben Quesada Lopez updated CALCITE-2930:
-----------------------------------------
Description:
FilterCorrelateRule#onMatch method executes the following:
{code:java}
public void onMatch(RelOptRuleCall call) {
final Filter filter = call.rel(0);
final Correlate corr = call.rel(1);
...
RelOptUtil.classifyFilters(
corr,
aboveFilters,
JoinRelType.INNER,
false,
!corr.getJoinType().toJoinType().generatesNullsOnLeft(), // *** HERE!
!corr.getJoinType().toJoinType().generatesNullsOnRight(), // *** HERE!
aboveFilters,
leftFilters,
rightFilters);
...
{code}
If the Correlate object has SemiJoinType SEMI (or ANTI), the
{{corr.getJoinType().toJoinType()}} will throw a IllegalStateException:
{code}
Caused by: java.lang.IllegalStateException: Unable to convert SEMI to
