> Issue Type: Bug
> Components: Metastore
> Affects Versions: 0.10.0
> Reporter: Travis Crawford
> Assignee: Travis Crawford

> This issue was discovered in HIVE-2585 and more details about why this issue
> was filed are available there.
> Currently if one sets {{hive.metastore.uris}} the following error will always
> be displayed:
> {code}
> 2012-07-24 15:23:58,647 [main] WARN org.apache.hadoop.hive.conf.HiveConf -
> DEPRECATED: Configuration property hive.metastore.local no longer has any
> effect. Make sure to provide a valid value for hive.metastore.uris if you are
> connecting to a remote metastore.
> {code}
> The reason is {{javax.jdo.option.ConnectionURL}} has a default value and will
> never be null. I set this property in {{hive-site.xml}} and walked through
> the configuration loading in a debugger. If the value is not empty it takes
> effect, and is ignored if empty.
> Since {{javax.jdo.option.ConnectionURL}} has a default and cannot be unset,
> this warning will always be printed if someone sets {{hive.metastore.uris}}.
> Per the review comments, the error message was added to reduce user
> confusion, and prevent surprises by using the wrong metastore (either
> embedded or remote). In {{HiveMetaStoreClient.java}} we see a very clear info
> message printed saying that a remote metastore is used.
> {code}
> LOG.info("Trying to connect to metastore with URI " + store);
> ...
> LOG.info("Connected to metastore.");
> {code}
> Since we clearly communicate to the user that a remote metastore at the given
> URI is being used we'll remove that message. Additionally, to further clarify
> a remote metastore is used I'll make the following HiveMetaStoreClient
> logging change:
> {code}
> LOG.debug("Trying to connect to remote HiveMetaStore: " + store);
> ...
> LOG.info("Connected to remote HiveMetaStore: " + store);
> {code}
> The change is at debug level we print connection attempts, and always print
> which remote HiveMetaStore we actually connected to.
