Thanks, this is very useful. How would one go about getting the application name? Is it the app name or the app ID or something else? Thanks!

buntu · ‎05-01-2017

Thanks for the update. > Are you looking for support on a particular environment? Yes, looking for Debian (Wheezy or Jessie) support.

Trying to understand the requirements for CDSW which seems to be only available on RHEL/CentOS: https://www.cloudera.com/documentation/data-science-workbench/latest/topics/cdsw_requirements_supported_versions.html#operating_system_req But docker containers are support across other linux distributions. Are there plans to make it available on other distributions?

I got 5 clusters managed by CM and everything is on the latest CDH 5.10. In order to evaluate the Java upgrade, I would like to test the upgrade on a test cluster and minimize the issues when upgrading the prod clusters.

buntu · ‎04-12-2017

Thanks for the response. Since CM host manages the clusters, I wanted to check if the hosts for one of the cluster (running the services) be running say Java 8 while CM host still be on Java 7?

buntu · ‎04-12-2017

Is it possible to have CM host running on a different version of Java compared to the Java version all the hosts of a cluster? Thanks!

buntu · ‎04-04-2017

Can anyone weigh in on the possibility of running the cluster hosts, except the cloudera manager host, on JDK 1.8? Thanks!

I run into this error when I try to start the NodeManager: ~~~~ Error starting NodeManager org.apache.hadoop.yarn.exceptions.YarnRuntimeException: org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Recieved SHUTDOWN signal from Resourcemanager ,Registration of NodeManager failed, Message from ResourceManager: Disallowed NodeManager from <host>, Sending SHUTDOWN signal to the NodeManager. at org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.serviceStart(NodeStatusUpdaterImpl.java:215) at org.apache.hadoop.service.AbstractService.start(AbstractService.java:193) at org.apache.hadoop.service.CompositeService.serviceStart(CompositeService.java:120) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.serviceStart(NodeManager.java:288) at org.apache.hadoop.service.AbstractService.start(AbstractService.java:193) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartNodeManager(NodeManager.java:522) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.main(NodeManager.java:568) Caused by: org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Recieved SHUTDOWN signal from Resourcemanager ,Registration of NodeManager failed, Message from ResourceManager: Disallowed NodeManager from <host>, Sending SHUTDOWN signal to the NodeManager. at org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.registerWithRM(NodeStatusUpdaterImpl.java:283) at org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.serviceStart(NodeStatusUpdaterImpl.java:209) ~~~~~~ Any idea how to overcome this error and start the NodeManagers?

While attempting to apply a host template, I keep running into this error/notification: Host must have a single version of CDH installed I didn't notice multiple cm agents running on the host, is there anything else I need to check? Thanks!

buntu · ‎03-16-2017

CDH and Cloudera Manager requirements are mentioned here: https://www.cloudera.com/documentation/enterprise/release-notes/topics/rn_consolidated_pcm.html "... Cloudera does not support mixed environments, all nodes in your cluster must be running the same major JDK version." If I want to run the hosts of the cluster on JDK 8, can I still have CM running on JDK 7? Thanks!

buntu · ‎03-12-2017

I currently have my CDH 5.9 cluster currently on JDK 1.7 and wanted to know if its safe to upgrade the hosts to JDK 1.8. Also, is it possible to have the Cloudera manager to be on JDK 1.7 while the cluster to be upgraded to JDK 1.8. Thanks!

How does one go about deploying a Spark streaming job on a CDH cluster? Does the job need to be deployed as a CSD parcel? Thanks!

buntu · ‎02-01-2017

Ok, I do notice the CDH 5.10 parcel and requires Cloudera Manager to be updated before updating CDH parcel.

buntu · ‎02-01-2017

Is this still the right way to configure the repo URL and get the latest CDH when available: http://archive.cloudera.com/cdh5/parcels/{latest_supported}/ I don't seem to find CDH 5.10 via Cloudera Manager. If I look at the 'latest' directory I notice the CDH version is 5.3.10: http://archive.cloudera.com/cdh5/parcels/latest/ Please let me know if the repo URL needs to be updated. Thanks!

buntu · ‎01-16-2017

Is there a R package/parcel that is available to be installed across the CDH cluster? Thanks!

buntu · ‎01-12-2017

Given the size of the dataset, I believe the data fits in memory and its not providing any additional performance improvement. Thanks!

buntu · ‎01-11-2017

I got a table of size ~1gb and I tried to setup hdfs caching as described in this 'Using HDFS caching with Impala" doc, with replication factor of 2 I noticed that without hdfs caching the queries seem to be performing better. I'm using CDH 5.8.2. Is there anything I might be missing or can check why that is the case? Thanks!

buntu · ‎01-10-2017

Any update on if this will be made available by Continuum or Cloudera anytime soon? Thanks!

buntu · ‎01-04-2017

I currently have this configured for the Anaconda parcel: https://repo.continuum.io/pkgs/misc/parcels/ This repo doesn't seem to have the Jessie compatible version of the parcel. Is there any other repo with the appropriate version of Anaconda parcel? Thanks!

buntu · ‎10-31-2016

Thanks for the tutorial. Are there any workflow examples of how to handle the update and delete transactions and how to replicate it into HBase/Phoenix?

buntu · ‎08-18-2016

When using "--as-parquetfile" option to do "--hive-import", I'm running into this error: org.kitesdk.data.DatasetNotFoundException: Unknown dataset URI pattern: dataset:hive://<metastore>:9083/<table> Check that JARs for hive datasets are on the classpath I've also passed the options to set the HIVE_HOME and HCAT_HOME: --hive-home /opt/cloudera/parcels/CDH/lib/hive --hcatalog-home /opt/cloudera/parcels/CDH/lib/hive-hcatalog Is there anything else that need to be provided to the sqoop action in oozie? Thanks!

buntu · ‎05-27-2016

Any update on if and when CDH for Debian 8.0 might be released?

buntu · ‎05-23-2016

Hi -- How does one go about setting limits on number of queries that a user can run, limits on number of resources (cpu cores, memory etc) a user can use via CM? Thanks!

buntu · ‎04-26-2016

I got multiple clusters and would like to move some nodes between clusters managed by Cloudera Manager. Is there any documentation on how to move node(s) from one cluster to another? Do the nodes need to be running on the same version of CDH? Thanks!

buntu · ‎04-13-2016

How does one go about installing CDH on Debian 8.0? Currently only wheezy parcels seem to be available.

buntu · ‎04-11-2016

Thanks for the info, I'm currently using CM 5.5.0. Will upgrade and verify the parcel.

buntu · ‎04-11-2016

I'm currently using CDH 5.5.1 and only notice parcel for 5.5.2 available for upgrading the cluster. I notice that there is 5.6.x and 5.7.x released but they do not show up as being available. Is there anything that needs to be configured? Thanks!

buntu · ‎02-22-2016

Thanks srowen! I did notice that I'm able to import 'spark.graphx._' but in the known issues for CDH 5.5 its marked as not supported so was checking: http://www.cloudera.com/documentation/enterprise/latest/topics/cdh_rn_spark_ki.html "GraphX not supported Cloudera does not support GraphX." It probably means its not supported in these forums 🙂

buntu · ‎02-22-2016

Is Graphx avaiable in the latest CDH distro? How to check if a specific pkg or lib is available in CDH in general? Thanks!

buntu · ‎02-22-2016

Currently using CDH 5.5.1 which has with Spark 1.5. Since there is already Spark v1.6, I wanted to know how the Cloudera community is deploying any newer versions while also handling the CDH upgrade scenarios. It will be really helpful if there is any recommended way to handle these without much hassle. Thanks!
