Hello, I would like to know the various activities performed by respective users on Cloudera Manager. For example, which user restarts a service or moves a cluster / service to maintenance mode. Would be great if any one could share some information on this. Thanks snm1523

Hello, I am trying to deploy a POC cluster using Path A of Cloudera Manager installation documentation. However, it is failing with below message in the logs: cat 5.install-cloudera-manager-server-db-2.log
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Resolving Dependencies
--> Running transaction check
---> Package cloudera-manager-server-db-2.x86_64 0:5.15.1-1.cm5151.p0.3.el7 will be installed
--> Processing Dependency: postgresql-server >= 8.4 for package: cloudera-manager-server-db-2-5.15.1-1.cm5151.p0.3.el7.x86_64
--> Finished Dependency Resolution
Error: Package: cloudera-manager-server-db-2-5.15.1-1.cm5151.p0.3.el7.x86_64 (cloudera-manager)
Requires: postgresql-server >= 8.4
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest I also tried to use local repository and point .bin file using --skip_repo_package=1. However, Was unable to find packages for PostgreSQL 8.4 any where, so created repo of 9.6 instead. CM at the first place hunts for PostgreSQL 8.4, and then finds 9.6 in the repo, however, fails at dependency check. It still needs few dependent packages (5-6) to proceed. Before I download each package and put it in repo, seeking suggestions / help from the community on why is the installation with Cloudera repos (installation path A) failing with that message. Thanks snm1523

Hi Jaimie, Just did a little google and found below things to be set. This may resolve the issue: set hive.tez.container.size=2048;
set hive.tez.java.opts=-Xmx1700m; --set this 80% of hive.tez.container.size Please give it a try if you feel confident on this. Thanks snm1502

Hello, We have been getting regular warning messages of Swap Memory being utilized more than the threshold limit. Currently, we have set swap memory threshold as below: For, HDFS = 100 MB Impala = 30 MB Yarn = 500 MB (Could be +-20%, I dont remember the exact number). Swap Memory usage for each of the component is crossing the threshold and reaches upto 720 MB (in case of Yarn). Because of this, we usually see warnings on our CM dashboard. I know increasing the Swap Memory Threshold could remove these warnings, however, we would prefer rather reducing the usage. Would be great if anyone could suggestion any Memory Tuning options which would reduce the usage of Swap Memory. Also, if there is a best recommendations of setting memory usage threshold, kindly share that as well. Thanks Snm

Hello, I was able to find a solution to this issue. You would need to add below property to mapred-site.xml basis on your Hadoop version: Hadoop 1.x: <property>
<name>mapred.job.tracker</name>
<value>localhost:9101</value>
</property> Hadoop 2.x: <property>
<name>mapreduce.jobtracker.address</name>
<value>localhost:9101</value>
</property> Thanks snm1523
