Review request for hive and Prasanth_J.
Bugs: HIVE-17611
https://issues.apache.org/jira/browse/HIVE-17611
Repository: hive-git
Description
-------
Create new LazyBinarySerDe2 class which derives from LazyBinarySerDe.
Avoid the ObjectInspector getCategory()/getPrimitiveCategory() calls for every
row/column by making those calls during initialization and creating
serialization objects for each column. Then serialization of the row is just a
matter of calling serialize() on these pre-initialized objects.
