> For SMBJoin, BucketizedHiveInputFormat should(could?) be used with set 
> command.
> {noformat}
> set hive.input.format = 
> org.apache.hadoop.hive.ql.io.BucketizedHiveInputFormat;
> {noformat}
> But this affects all of the MR taks in a query, which might not be intended. 
> With some configuration, it should be automatically configured only for MR 
> tasks which contains SMBJoin.
