table is not working".

  Some minor comments + request for more info.

INLINE COMMENTS
  ql/src/java/org/apache/hadoop/hive/ql/Driver.java:600 tableScanOperator was actually a clearer
name, wasn't it?
  ql/src/java/org/apache/hadoop/hive/ql/exec/MapOperator.java:108 I think this is redundant.
o instanceof MapInputPath is false if o == null
  ql/src/java/org/apache/hadoop/hive/ql/optimizer/ppr/PartitionPruner.java:134 can you please
add a javadoc comment here?
  ql/src/java/org/apache/hadoop/hive/ql/exec/MapOperator.java:18 There are a lot of changes
in MapOperator. I've scan through them and it seems most (all?) are just cleaning up the operator
(which is great).

  Is that correct? If not can you please point out what the important changes are?
