LocalMapJoinProcFactory (Hive 1.2.2 API)

```
public final class LocalMapJoinProcFactory
extends Object
```
Node processor factory for map join resolver. What it did is to replace the map-join operator in the local map join task with a hash-table dump operator. And if the map join is followed by a group by, the hash-table sink operator/mapjoin operator should be configured to use less memory to avoid OOM in group by operator.
