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.
