-----------------------------------------------------------------
[~prasanth_j] can you take a look? Note this also fixes the usage in Reduce and
Merge processors where close() uses the "cache" field, but that field is never
initialized - instead, ctors use a local variable.

> 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
