> Project: Calcite
> Issue Type: Bug
> Reporter: Ruben Quesada Lopez
> Assignee: Ruben Quesada Lopez
> Priority: Major

> 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(),
> !corr.getJoinType().toJoinType().generatesNullsOnRight(),
> 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 JoinRelType
> at org.apache.calcite.sql.SemiJoinType.toJoinType(SemiJoinType.java:83)
> at org.apache.calcite.rel.rules.FilterCorrelateRule.onMatch(FilterCorrelateRule.java:89)
