Travis Crawford commented on HIVE-2585:
---------------------------------------
I started seeing this error message in my logs, and when investigating believe
there's an issue here. AFAICT, if you set {{hive.metastore.uris}} you will
ALWAYS see this error.
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}}.
Before diving into possible solutions, [~ashutoshc] & [~appodictic] can you
confirm this is an issue, or clarify how to correctly configure this? If this
is a user error I can post a patch clarifying the error message so others that
see this message will know what to do.

those config key" +
+ "in configuration");

> We should just have hive.metastore.uris. If it is empty, we shall assume
> local mode, if non-empty we shall use that string to connect to remote
> metastore. Having two different keys for same information is confusing.
