Overview
...
Once finished, the install server has started a web server on 7180, so tunnel that port to a local port (eg 7180!) using ssh and visit that "localhost" page on your local browser (or access the page directly if you are directly connected to the node).
User interface phase - installation
Login using admin/admin
Select "Cloudera Express" and "Continue" twice (until you get to the "Specify hosts for your CDH cluster installation")
Add the hostnames for the nodes you want to add to the cluster, "Search" and "Continue" (assuming the right hostnames appeared)
On the "Cluster Installation" page, accept the defaults and "Continue".
On the page after that, select the "Install Oracle Java SE Development Kit" option and "Continue".
On the page after that, ignore the "Single User Mode" option and "Continue".
The next page requires you to select the SSH login credentials. For most systems, this involves uploading an ssh key. Don't forget to set the key passphrase if one is specified. Only 1 simultaneous installation need be specified.
"Continue" on, which will start the installation. Once that is done "Continue" again, to move to another automatic installation page ("Installing Selected Parcels"). "Continue" once that is done.
The next page is the "Host inspector" - this page will provide warnings and errors. The following warnings can be ignored:
- "Cloudera recomments settings /proc/sys/vm/swappiness to 0"
- "There are mismatched versions across the system, which will cause failures. See below for details on which hosts are running what versions of components"
- (this just refers to Java)
- "Cloudera supports versions 1.6.0_31 and 1.7.0_55 of Oracle's JVM and later. OpenJDK is not supported, and gcj is known to not work. Check the component version table below to identify hosts with unsupported versions of Java."
Other reported issues may cause problems.
If there are no unexpected issues, then hit "Finish". This will take you to the configuration phase described below.
| Warning |
|---|
In my experience if you have to go "Back" at any point, or have to refresh the browser at any stage, then the install as a whole should be considered compromised. If this occurs then run "/opt/hadoop-infinite/scripts/uninstall_cd5.sh" on all nodes and then restart the install from the beginning. |
User interface phase - configuration
