With the latest releases of CDH, Impala is included in the CDH parcel itself and doesn't need a separate repository. The current version of Impala in CDH 5.11.1 is 2.8.0, see this URL: https://www.cloudera.com/documentation/enterprise/release-notes/topics/cdh_vd_cdh_package_tarball_511.html   So this means, if you're able to create a CDH cluster on a bunch of CentOS 7 hosts, you should be able to add the Impala service as well. Please don't add that parcel quoted above as it's not required any longer. ... View more

Vik11, you can work around this by setting Java's tmp dir to something other than /tmp. This solution has worked in the past for a customer, YMMV. Of course that mount point should not have noexec set.   In YARN configuration append '-Djava.io.tmpdir=/path/to/other/temp/dir' to the following properties: 1. ApplicationMaster Java Opts Base 2. Java Configuration Options for JobHistory Server 3. Java Configuration Options for NodeManager 4. Java Configuration Options for ResourceManager For jobs: Cloudera Manager --> YARN --> search for: Gateway Client Environment Advanced Configuration Snippet (Safety Valve) for hadoop-env.sh and add this: HADOOP_CLIENT_OPTS="-Djava.io.tmpdir=/path/to/other/temp/dir"   Now redeploy YARN client configuration. ...

Yes, by deleting it from the list, Cloudera Manager will automatically remove it from the ensemble and update the config files of the other three servers. They would need a restart to see the change. ... View more

4 is not an ideal number. I'd suggest you simply stop and delete the "down" ZooKeeper server from Cloudera Manager. It will remove the server from the ensemble, you'd have to restart all of ZooKeeper to enforce the change. ... View more

The message implies you must have 1,3,5,7,... ZooKeeper servers in the cluster. It doesn't matter if they're running or not at the time. How many ZooKeeper servers do you have within the service? ... View more

Does your "cluster" definition look like this? The CDH property should be the version, not the entire parcel name   cluster {     products {       CDH: 5.4.7     }     parcelRepositories: [         "http://archive.cloudera.com/cdh5/parcels/5.4.7/"     ] } ... View more
