@Amn_468 Your approach looks fine. You can always follow the recommendations while doing maintenance of cluster by referring below doc which is very informative. https://docs.cloudera.com/documentation/enterprise/5-14-x/topics/cm_mc_host_maint.html

@mike_bronson7 For the installation purpose we have a very nice community article which you can follow where you will get all types of installation method with videos[1]. The package installation is almost deprecated since it's hard to manage a cluster in RPM. Though you can try for personal purposes, here is the doc. https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_ig_custom_installation.html#cmig_topic_21_2 Regarding some other some other knowledge and videos you can follow Cloudera Youtube[2] channel as well as Blog[3]. https://community.cloudera.com/t5/Community-Articles/How-To-Path-B-Installation-of-Cloudera-Manager/ta-p/44598 https://www.youtube.com/c/ClouderaInc/playlists https://blog.cloudera.com/

@Mondi As far as I know real time replication is not possible but tow cluster can be in sync using BDR feature. https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_bdr_replication_intro.html

@Marek Parcels can be downloaded. This is strange I am not able to reproduce though. Can you please deactivate the CDSWc parcels and then remove the CSD and again download a fresh one and restart the CM server form terminal and let me know how this goes.

@Marek Please add the CSD (jar file) in the CM first as per your CDH version by following the doc below: https://docs.cloudera.com/documentation/data-science-workbench/1-7-x/topics/cdsw_install_parcel.html#csd Then restart the CM server and you will hopefully get the Parcels listed there for CDSW.

It was either written with less repicas by the client, or someone changed it after it was written. For example Solr Tlogs I believe are written with a replica of 1. Each DFSClient has the ability to control the number of replicas. As said, Solr uses 1 for Tlogs, MR uses (or used to use) 10 for job files for better chance of data locality. It’s a decision made by whoever creates the client. So it is expected that any file can have a different replication factor, within the limits of dfs.namenode.replication.min and dfs.replication.max which is enforced by the NameNode.

@wert_1311 You can use the HDFS command line to ls the file. The second column of the output will show the replication factor of the file. For example, $ hdfs dfs -ls /usr/GroupStorage/data1/out.txt
-rw-r--r-- 3 hadoop test 11906625598 2020-04-29 17:31 /usr/GroupStorage/data1/test Here the replication factor is 3.

@EnableMe For trial version you have to follow the steps on Given Link.

Trial Installation Ideal for trying CDP Data Center for the first time, this installer will download Cloudera Manager and guide you through the setup process. This creates a self-contained environment and doesn’t require installing any additional software. Users setting up CDP Data Center for production use should not use these instructions but instead follow the installation instructions in CDP documentation. Note: A trial installation cannot easily be upgraded, backed up, or migrated into a production-ready configuration without manual steps, described here. If you plan to migrate this system into a production system, consider using the Production Installation process described here instead. Pre-requisites: Creating a CDP cluster requires multiple, Internet-connected Linux machines. For details please see the CDP system requirements. Installation instructions: Type the following at a Linux command prompt to begin an automated CDP installation. $ wget https://archive.cloudera.com/cm7/7.0.3/cloudera-manager-installer.bin $ chmod u+x cloudera-manager-installer.bin $ sudo ./cloudera-manager-installer.bin
