We have CDH 5.5.2 installed using Cloudera Manager. Hive is not installed.   When using spark-submit or spark-shell, we get a lot of errors apparently related to Hive, but Spark works fine.   Grepping out the exceptions without the long stacktraces, the errors are Caused by: java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:derby:;databaseName=/var/lib/hive/metastore/metastore_db;create=true, username = APP. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------ java.sql.SQLException: Failed to create database '/var/lib/hive/metastore/metastore_db', see the next exception for details. Caused by: ERROR XJ041: Failed to create database '/var/lib/hive/metastore/metastore_db', see the next exception for details. Caused by: ERROR XBM0H: Directory /var/lib/hive/metastore/metastore_db cannot be created.   The last exception is: Caused by: ERROR XBM0H: Directory /var/lib/hive/metastore/metastore_db cannot be created. at org.apache.derby.iapi.error.StandardException.newException(Unknown Source) at org.apache.derby.iapi.error.StandardException.newException(Unknown Source) at org.apache.derby.impl.services.monitor.StorageFactoryService$10.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at org.apache.derby.impl.services.monitor.StorageFactoryService.createServiceRoot(Unknown Source) at org.apache.derby.impl.services.monitor.BaseMonitor.bootService(Unknown Source) at org.apache.derby.impl.services.monitor.BaseMonitor.createPersistentService(Unknown Source) at org.apache.derby.impl.services.monitor.FileMonitor.createPersistentService(Unknown Source) at org.apache.derby.iapi.services.monitor.Monitor.createPersistentService(Unknown Source)   Any idea how to suppress these unnecessary errors?   Craig ...
