Hive Unable to start due to metastore exception
-----------------------------------------------

                 Key: HIVE-1554
                 URL: https://issues.apache.org/jira/browse/HIVE-1554
             Project: Hadoop Hive
          Issue Type: Bug
          Components: CLI, Metastore, Server Infrastructure
    Affects Versions: 0.5.0
         Environment: Suse Linux v 11, Hadoop v .20.1. , Derby10.5.3
            Reporter: Soundararajan Velu


Hive is running after restared some time it is not starting because of metastore excepiton
. The exception is like this

2010-08-17 09:17:03,916 ERROR metastore.HiveMetaStore (HiveMetaStore.java:<init>(107))
- Unable to initialize the metastore :Exception thrown performing schema operation : Add classes
to Catalog "", Schema "APP"

We are using Derby10.5.3 in server mode  we have connected to derby through this URL     
                                       jdbc:derby://{IP}:{PORT}/metastore_db;create=true.


If i remove   metastore_db   from the derby/bin location it is starting and creating new metastore_db
in derby/bin.  I suspect metastore_db is corrupted but i am able to open the same metastore_db
through the squirrel client.

Here my doubt is metastore_db corrupted or some other problem. If it is corrupted how to recover
the db.
