> {code:java}
> // disable filter pushdown for mapreduce when there are more than one table
> aliases,
> // since we don't clone jobConf per alias
> if (mrwork != null && mrwork.getAliases() != null &&
> mrwork.getAliases().size() > 1 &&
> jobConf.get(ConfVars.HIVE_EXECUTION_ENGINE.varname).equals("mr")) {
> return;
> }
> {code}
> I believe this needs to be handled at OpProcFactory so that hive doesn't
> believe that predicate is handled by storage handler.
