Bugs: AMBARI-10489
https://issues.apache.org/jira/browse/AMBARI-10489
Repository: ambari
Description
-------
This patch resolves AMBARI-10489 and AMBARI-10488.
This patch includes some minor changes to the Blueprint configuration processor
in order to support Blueprint deployments of HiveServer2, Hive MetaStore,
and WebHCat servers in a High Availability mode.
This patch implements the following:
- Updates the property updater implementations in the
BlueprintConfiguration processor in order to properly handle the cases
when more than one instance of HiveServer2, HiveMetaStore, or WebHCat
services are included in a Blueprint. When an HA scenario is
detected by the Blueprint processor, multiple instances of each of
these services is now supported.
- Updates to the MultipleHostPropertyUpdater implementation, in
order to properly support the syntax of the "hive.metastore.uris"
property in hive-site, which can consist of a comma-separated
list of thrift:// URLs.
- Modified the updater for "hive.metastore.uris" to refer to
the HIVE_METASTORE component, rather than HIVE_SERVER,since this
property should point to metastore servers.
- Implements a new PropertyUpdater, TempletonHivePropertyUpdater,
in order to support the proper updating of the "hive.templeton.properties"
configuration value.
- Updates the HDP 2.2 stack defintion for Hive, such that the
WEBHCAT_SERVER component has a new cardinality of "1+", so that
multiple instances of this component will be allowed in a
given cluster.
- Implements new unit tests to verify these changes, and also updates
existing tests to accomodate for the changes.

Testing
-------
1. Ran ambari-server unit tests (all passing)
2. Verified that I can deploy a Hive HA cluster using a Blueprint to a 3-node
cluster. This cluster contains two of each of the following components
(HiveServer2, Hive MetaStore, WebHCat).
3. Ran a simple, single-node cluster deployment with the Ambari UI, including
Hive, to make sure my minor stack change did not break anything in the UI
deployment.
Thanks,
Robert Nettleton
