derbyclient.jar and derbytools.jar show ship with hive
------------------------------------------------------

                 Key: HADOOP-4332
                 URL: https://issues.apache.org/jira/browse/HADOOP-4332
             Project: Hadoop Core
          Issue Type: Improvement
          Components: contrib/hive
         Environment: Cent OS 5 x86-64 JDK 1.6
            Reporter: Edward Capriolo
            Priority: Minor


Attempting to use the Derby ClientDriver will cause a null pointer exception. 

derbyclient.jar and derbytools.jar
javax.jdo.option.ConnectionDriverName=org.apache.derby.jdbc.ClientDriver

hive> show tables;
08/10/02 15:17:12 INFO hive.metastore: Trying to connect to metastore
with URI jdbc:derby://nyhadoop1:1527/metastore_db
FAILED: Error in semantic analysis: java.lang.NullPointerException
08/10/02 15:17:12 ERROR ql.Driver: FAILED: Error in semantic analysis:
java.lang.NullPointerException

derbyclient.jar and derbytools.jar should probably be put in the hive/lib 
directory. Also this type of exception not having the appropriate driver should 
be trapped and reported differently if possible.
