    Description

      Before releasing with the updated KuduStorageHandler, we should change the new KuduStorageHandler package from “org.apache.kudu.hive” to “org.apache.hadoop.hive.kudu”.

       

      This should being done to ensure the stand-in storage handler can be a real storage handler when a Hive integration is added in the future. The “org.apache.hadoop.hive” package is the standard package all Hive storage handlers lives under.

       

      Additionally the stand-in format details defined here should be updated as well. Values for those entries should be:

      org.apache.hadoop.hive.kudu.KuduInputFormat
      org.apache.hadoop.hive.kudu.KuduOutputFormat 
      org.apache.hadoop.hive.kudu.KuduSerDe 
      

       

      I have a WIP patch for HIVE-12971 and used that patch to validate that using "correct" stand-in values would allow Hive to read HMS tables/entries created by Impala. 

       

      Note: This patch will need to be committed after the Kudu side patch is committed and the Kudu build/version may need to be update in Impala. A review for the Kudu side change is here: https://gerrit.cloudera.org/#/c/13540/
