[jira] [Created] (MAPREDUCE-7347) Add a Hive platform to Nativetask

Song Jiacheng created MAPREDUCE-7347:
----------------------------------------

             Summary: Add a Hive platform to Nativetask
                 Key: MAPREDUCE-7347
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7347
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 3.2.1
            Reporter: Song Jiacheng


For now, Native task can not be used by Hive job, because we need to register the key.

And as we all know, HiveKey, which is the key in Hive job, is a child class of BytesWritable.

So what we need to do is just register the HiveKey as BytesWritable.

This solution has already used online in our cluster, we got tens of thousands sqls submitted to the cluster.
