Hi,
Additionally, verify this property

<property>
  <name>javax.jdo.option.ConnectionURL</name>
  <value>jdbc:derby:;databaseName=metastore_db;create=true</value>
  <description>JDBC connect string for a JDBC metastore</description>
</property>

in hive-default.xml

Hi Periya,

Try removing both .lck (lock) files in the metastore_db folder. The derby db can only support one user. So if you have used hive from cli it is probably for another user.

Cheers, Jasper

Hi Vivek,
   Tried doing with sudo and later also changed the permissions. None of them worked.

try issuing with "sudo".  as metastore_db is locked for root user.
else do sudo chmod 777 <metastore_db> folder.

Subject: Hive server not starting...on EC2 Ubuntu 10.04 instance

Hi all,
   I am trying to start hive server, but, after the command, it looks like nothing is happening. 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.
