MetaStore ConnectionURL updates need to trigger creation of Default DB if it
doesn't exist
------------------------------------------------------------------------------------------
Key: HIVE-2029
URL: https://issues.apache.org/jira/browse/HIVE-2029
Project: Hive
Issue Type: Bug
Components: Metastore
Affects Versions: 0.7.0
Reporter: Carl Steinbach
HIVE-1219 defined the JDOConnectionURLHook plugin, and integrated this feature
into HiveMetaStore. On MetaStore operation failures, this plugin is used to
update the metastore ConnectionURL configuration property. Currently this
update triggers the reinitialization of the underlying JDO PersistenceManager,
but it does not trigger checks to see if the default database exists, nor will
it create the default database if it does not exist. It needs to do both.
This ticket also covers removing the 'hive.metastore.force.reload.conf'
property from HiveConf and HiveMetaStore. This property should not have been
added in the first place since its sole purpose is to facilitate testing of the
JDOConnectionURLHook mechanism by unnaturally forcing reinitialization of the
PersistenceManager.
