Below are the custom properties which would go in hand with H2O Sparkling Water . Use these properties to modify H2O Cluster Nodes, Memory, Cores etc.

Short Description: Configure Knox to access Atlas UI Article Here is the steps to access Atlas UI through Knox. 1. Make sure Knox is configured properly and it works fine. 2. ssh to Knox gateway host and go to /var/lib/knox/data-2.6.****/services 3. mkdir –p atlas/0.8.0/ mkdir –p atlas-api/0.8.0/ 4. download the configurations from https://github.com/apache/knox/tree/v0.13.0/gateway-service-definitions/src/main/resources/services/atlas-api/0.8.0 URL to /var/lib/knox/data-2.6.***/services/ atlas-api/0.8.0/ 5. download the configurations from https://github.com/apache/knox/tree/v0.13.0/gateway-service-definitions/src/main/resources/services/atlas/0.8.0 URL to /var/lib/knox/data-2.6.***/services/ atlas/0.8.0/ 5. change the owner/Group permissions to Knox for /var/lib/knox/data-2.6.**/services/atlas*/ and subdirectory 6. Go to Knox configurations Modify "Advanced topology" with below service tag <service> <role>ATLAS</role> <url>sandbox.hortonworks.com:21000</url> </service> <service> 7. Restart Knox service. 8. You should be able to access Atlas UI from the below URL https://sandbox.hortonworks.com:8443/gateway/default/atlas/ Please Note: At this point of time, it's a work-around, Hortonworks doesn't support this yet.

Cluster is kerberized with knox installed. I am trying to access hive using beeline without knox works fine but with knox URL it gives below error.

Issue: On Adding Oozie service to cluster, sometimes its possible user could see an error with simple message Failed to create new war file as below and on top of it Oozie server wouldn't start. INFO: Adding extension: /usr/hdp/current/oozie-server/libext/mysql-jdbc-driver.jar Failed: creating new Oozie WAR Solution: Oozie deployment script is trying to unzip the existing Oozie war file and then zip it back up and place it in a sub directory of /tmp/... . This unzip and zip process doubles the storage space required for the Oozie war file. Make sure there is enough /tmp storage for the above process to take place, logs wouldn't provide this info.

Any pointers for deploying and reconfiguring the Spark work processes in GPUs.

Noticed scheduler option under each notebook in Zeppelin, was wondering if there is a scheduler overview page which shows all the scheduled notebooks and run job status.

Resolution/Workaround: - Clear any value assigned to the Hive Configuration Resources property in the PutHiveStreaming processor. (With no site.xml files provided, NiFi will use the site.xml files that are loaded in the classpath). - To load the site.xml files (core-site.xml, hdfs-site.xml, and hive-site.xml) on NiFi's classpath, place them in NiFi's conf directory (for Ambari based installs that would be in /etc/nifi/conf) - Restart NiFi.

Thanks all for your comments. Looks like earlier upgrade missed below step, ambari-server stop ambari-server upgradestack HDP-2.3 ambari-server start This was evident from ambari database tables, while finalizing earlier upgrade, it errored out.

kjilla · ‎07-10-2016

yes, upgraded current prod cluster from Ambari 2.2.1.1 to 2.2.2 and we are trying to upgrade HDP from 2.3.4.7 to 2.4.2. Able to perform the same in pre-prod env without issues.

Since storm was never used in the cluster, customer didn't want to spend time in research, service was removed.

please refer http://docs.hortonworks.com/HDPDocuments/Ambari-2.1.2.0/bk_ambari_views_guide/content/_reverse_proxy_views.html

kjilla · ‎06-01-2016

solved the issue by updating mapred.admin.user.env , since the cluster was upgraded from HDP 2.1 to HDP 2.3

Does it mean if the cluster is kerberized, we don't need Knox ? Only Ranger installation is enough.

kjilla · ‎03-03-2016

My client has the similar issue which fails while the job being submitted using capacity scheduler, where it works fine with fair scheduler.

kjilla · ‎03-02-2016

To configure this scenario, schedule-based policies are used. This is an alpha Apache feature, but i was not able to find any documentation associated . Can you please someone share if they had any.

kjilla · ‎03-02-2016

Thanks, that helps. At the same time, can you point me to Setting Up Time-Based Queue Capacity Change.

How can we configure cluster to have spark separated from other echo system components
