Review request for Ambari and Dmitro Lisnichenko.


Bugs: AMBARI-6684
    https://issues.apache.org/jira/browse/AMBARI-6684


Repository: ambari


Description
-------

Ambari should support installation and management of multiple Hive metastore servers for High
Availability, with appropriate setting of hive.metastore.uris for metastore clients, and configuration
of hive properties such as hive.cluster.delegation.token.store.class for proper coordination.
Multiple metastores have been supported for some time (http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.1/bk_system-admin-guide/content/sysadminguides_ha_chap3.html),
but Ambari 1.6 will not create a 2nd (or more) metastore server via the GUI. The idea would
be for Ambari to support adding more metastore servers and for hive-site.xml on the hive client
nodes to be configured with a multi-server URI in hive.metastore.uris as described in the
web page above.
