Krishna Kumar updated HIVE-956:
-------------------------------

    Attachment: HIVE.956.patch.1

Patch with a change on how null vs empty strings are handled. This patch uses a 
special single-byte marker (which is not a valid utf-8 byte sequence) to mark 
empty strings. With this patch, this serde is better than the default serde
 - for all primitive types
 - also when null values preponderate
while performing about the same for complex structures such as list of structs 
et al. Please review.


> Add support of columnar binary serde
