Please also refer to this link which details the differences between the Express and Enterprise editions of CM http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_ig_feature_differences.html

There is no limit on how many nodes you can manage with Cloudera Manager, even if it's the express edition.

You could get this error if the secondary or standby namenode is not performing checkpointing correctly. Please verify the health of the following roles: - Standby Namenode (if HDFS-HA is enabled) - Secondary Namenode (if HDFS-HA is *not* enabled)

That's great news, thanks for the feedback

Here is an example of implementing Lambda architecture using Spark on CDH http://blog.cloudera.com/blog/2014/08/building-lambda-architecture-with-spark-streaming/

Sorry for the late response. What exact version of CDH 5.x are you running?

GautamG · ‎10-19-2014

It should be possible to any of the Java collection classes in your application. Have you tried it already and are you facing problems?

You are right about the reboot of the node. /var/run is a tmpfs and all content is deleted on reboot. The other option is to restart the CM agent with clean_restart. # service cloudera-scm-agent clean_restart Note that either way, all CDH roles on the node will be restarted.

Please do not run the impalad daemon directly from the command line in that fashion. You can use Cloudera Manager to start the service and use impala-shell to run your queries.

Thanks for the feedback. So if we understand correctly, you modified the region to one where the key exists and are now able to deploy your cluster.
