Soundararajan Velu updated HIVE-1554:
-------------------------------------
Description:
When I try to restart Hive, sometimes it fails with weird exception around
metastore.
Following is the error message that it spits out.
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 the metastore_db from derby/bin, it starts and creates a new
metastore_db in derby/bin. I suspect metastore_db gets corrupted for some
reason, but I am able to open the same metastore_db through other clients like
squirrel, DBexplorer etc...
Here my doubt is metastore_db corrupted or some other problem. If it is
corrupted how to recover the db.

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
