Hi James,   You can try the instructions you linked before you change over to a beta 2 cluster, but there's no guarantee that things will all work happily. Whenever there's a command-line script you need to run, look in the relevant CM service and/or role to see if that command can be run by CM instead. Instead of installing the new CDH packages, download, distribute, and activate the new CDH parcel. Don't try to use the CM cluster upgrade wizard. There's no reason I can think of that they won't all work, but it's not recommended either.   CM will of course support upgrades between non-beta releases.   Thanks, Darren ... View more

Api documentation for your version of CM is available in the upper right of the CM UI, under Help or Support.   Latest version is also availalable here: http://cloudera.github.io/cm_api/   To make changes to management service configuration, you'll want to post to the API endpoints documented here: http://cloudera.github.io/cm_api/apidocs/v5/path__cm_service_config.html for service configuration http://cloudera.github.io/cm_api/apidocs/v5/path__cm_service_roleConfigGroups_-roleConfigGroupName-_config.html for role configuration   Remember to use the 'full' config view to see all configuration options via the API, as described in the tutorials.   Thanks, Darren ...

I would try in the Hive forum I mentioned before to see if they can help. Would be nice to try and find a relevant log error as well, maybe in hdfs or hive. ... View more

Hi Andrew, Are you trying to run HiveServer or HiveServer2? The command you're running will start the old HiveServer, which is discouraged due to a lot of bugs and architectural issues. I'm assuming you are using Cloudera Manager since this is a Cloudera Manager forum. If not, then you may want to re-post in the Hive forum: http://community.cloudera.com/t5/Batch-SQL-Apache-Hive/bd-p/Hive This blog post can help explain some important aspects of using Hive in Cloudera Manager: http://blog.cloudera.com/blog/2013/03/how-to-set-up-cloudera-manager-4-5-for-apache-hive/ If using Cloudera Manager, you can search for any error messages from Hive, HDFS, and MapReduce (or YARN, whichever Hive is configured to use) Log Search. The log you pointed at is just the MR log, but if you are losing connections to hive, then the client and hive server (2) logs will be more interesting. You can also usually check /var/log/hive for hive server (2) logs. Thanks, Darren ... View more
