> Map and reduce processors do this:
> {noformat}
>     if (LlapProxy.isDaemon()) {
>       cache = new org.apache.hadoop.hive.ql.exec.mr.ObjectCache(); // do not cache plan
> ...
> {noformat}
> but merge processor just gets the plan. If it runs in LLAP, it can get a cached plan. Need to move this logic into ObjectCache itself, via a isPlan arg or something. That will also fix this issue for merge processor
