Subject [jira] [Commented] (DRILL-1273) In case of multiple storage plugins (with optimization rules), all the queries with "where" clause will fail.

Jacques Nadeau commented on DRILL-1273:
---------------------------------------

Actually, this shouldn't be needed.  The matches() method already does this check.  When were
you experiencing this problem as that should filter out any other matches?

> In case of multiple storage plugins with respective optimization rules (like predicate
push down), optiq optimizer will call onMatch() method on all the sub classes of "StoragePluginOptimizerRule".
> In this case, all the queries with "where" clause will fail with ClassCastException.
