The derby db can only support one user. So if you have used hive from cli it is probably for another user.

I am not even getting a prompt. Here are some details: - machine - EC2 Ubuntu 10.04 LTS - Hive version - 0.7.1-cdh3u2 (as seen from hive-default.xml) - Hadoop version - 0.20.2 - I currently have an embedded Derby database as my metastore. (Plan to move it to a remote MySQL DB later. For now, i am the only user). root@domU-12-31-39-0E-C9-33:/usr/lib/hive/conf# hive --service hiveserver Starting Hive Thrift Server <it just hangs here...nothing happens for 10 min..had to Ctrl-c to get out.> Looks like to it is unable to talk to the metastore. I am able to run hive shell, create, drop tables and run queries from the shell. ----------- I did the following: - # HIVE_PORT=10000 hive --service hiveserver (same problem) - Tried changing ports, but, same problem.
