granthenke opened a new pull request #733: HIVE-12971: Add Support for Kudu Tables
URL: https://github.com/apache/hive/pull/733
 
 
   This patch adds an initial integration for Apache Kudu backed tables
   by supporting the creation of external tables pointed at existing
   underlying Kudu tables.
   
   SELECT queries can read from the tables including pushing most
   predicates/filters into the Kudu scanners. Future work should
   complete support for Kudu predicates.
   
   INSERT queries can write to the tables. However, they currently
   use Kudu UPSERT operations when writing. Future work should
   complete support for INSERT, UPDATE, and DELETE.
   
   Note: The table properties and class names match the values used by
   Apache Impala when creating HMS entries for Kudu tables. This
   means tables created by Impala can be used by Hive and vice versa.
