Description

To work around issues with Hadoop's Configuration object, specifically it's addResource(InputStream), default configurations are written to a temp file (I think HIVE-2362 introduced this).

This, however, introduces the problem that once that file is deleted from /tmp the client crashes. This is particularly problematic for long running services like the metastore server.

Writing a custom InputStream to deal with the problems in the Configuration object should provide a work around, which does not introduce a time bomb into Hive.
