All: I've been setting up Hive using Derby in Server Mode as per the instructions here: http://wiki.apache.org/hadoop/HiveDerbyServerMode
After I've got everything finished I attempt to start Hive and run a 'show tables;' query. I get the following output: hive> show tables; FAILED: Error in metadata: javax.jdo.JDODataStoreException: Exception thrown performing schema operation : Add classes to Catalog "", Schema "APP" NestedThrowables: java.sql.SQLNonTransientConnectionException: A network protocol error was encountered and the connection has been terminated: the requested command encountered an unarchitected and implementation-specific condition for which there was no architected message FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask It appears that something is missing from my classpath? I've set the follow environment variables: HADOOP_HOME HIVE_HOME DERBY_HOME DERBY_INSTALL Is there something else I need set and/or do? Nathan
