Figured it out...some of the entries in core-site.xml were listing specific nodes instead of * ...changing that fixed my issues 🙂

When I try to upload a CSV from my local machine into Hive I get the error below. I've tried doing this with the admin, hdfs, and hive users: Any ideas what's going on?

Host had a hard reboot and now am getting an HTTP Error 500 when trying to access Cloudera Manager. The service was dead but the pid still existed, so I deleted the pid file and restarted the service - which shows as running, but still getting the HTTP error 500. Any ideas on what to check? Problem accessing /cmf/login. Reason: Error creating bean with name 'newServiceHandlerRegistry' defined in class path resource [com/cloudera/server/cmf/config/components/BeanConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public com.cloudera.cmf.service.ServiceHandlerRegistry com.cloudera.server.cmf.config.components.BeanConfiguration.newServiceHandlerRegistry()] threw exception; nested exception is java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

Update: I've manually added the --driver postgresql1-9.4.1208.jre6.jar to my import command to manually point to the driver - but I still get an error stating it could not load the driver... ERROR sqoop.Sqoop: Got exception running Sqoop: java.lang.RuntimeException: Could not load db driver class: postgresql1-9.4.1208.jre6.jar

I'm working on pulling a table in from a Postgres database, but am running into an error: ERROR manager.SqlManager: Error executing statement: java.sql.SQLException: No suitable driver found for jdbc:postgresql://xx.xx.xx.xx:5432 I've downloaded the postgresql-9.0-801.jdbc4.jar file and placed it in /var/lib/sqoop2/ of the node and restarted the Sqoop service, yet I still get the error above. Any ideas what I'm doing incorrectly?

If the problem is users leaving their shells open, I don't think I can trust them to add extra parameters to their CLI arugments to ensure they don't eat up extra resources (from their point of view, why would they care if they're using up my resources?). How about changing the spark-defaults.conf for the Gateway Default Group in CM? Would that accomplish what I'm looking for?

Thanks for the reply. Being new to CDH, I do have a question. In the general settings of Spark in CM I see there's an option to either turn dynamic allocation off or on. If I wanted to tweak some of the configs for dynamic allocation as listed on the project page (http://spark.apache.org/docs/latest/configuration.html#dynamic-allocation) - would I do so via the Advanced Configuration snippets?

Braundmeier · ‎05-16-2016

We have some users who start Spark shells and leave them open indefinitely. Without using dynamic resource allocation to deallocate executors - would it be possible to write something to poll YARN to determine if a Spark shell isn't doing anything, and after X time period of inactivity, kill it?
