Hi, I am trying to run mutliple hive jobs in parallel from the same working directory. A lot of the jobs fail with the following:
FAILED: Error in metadata: javax.jdo.JDOFatalDataStoreException: Failed to start database 'metastore_db', see the next exception for details. NestedThrowables: java.sql.SQLException: Failed to start database 'metastore_db', see the next exception for details. FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask Command exited with non-zero status 9 My guess is that multiple hive processes are trying to create or lock/write to the metastore_db directory. Is this needed? Is there a way to run multiple jobs from the same working directory? any help is welcome. thanks, - Vasilis
