Next run the script "/opt/hadoop-infinite/scripts/uninstall_cdh3.sh" on each node (API and DB - the script will fail harmlessly if the node does not currently run CDH3)
- (eg 'sh infinite_run_script_el6.sh <CLUSTER> "sh /opt/hadoop-infinite/scripts/uninstall_cdh3.sh" <HOSTS>' for enterprise users)
Then
First step
To uninstall CDH3 TODOThis completes the uninstall of CDH3.
Installing CDH5 (MRv1)
Command line phase
If you did not already do as a step under "Upgrading from CDH3", install/upgrade the latest "infinit.e-hadoop-installer" RPM (must be v0.5 or higher).
On each node in the cluster (API and DB nodes - regardless of whether Hadoop/HDFS will actually be running). TODO, run the "/opt/hadoop-infinite/scripts/online_install.sh" script.
- (eg 'sh infinite_run_script_el6.sh <CLUSTER> "sh /opt/hadoop-infinite/scripts/online_install.sh" <HOSTS>' for enterprise users)
Finally for the "command line phase", select a node on which to run the Cloudera Manager server, and run "sh /opt/hadoop-infinite/scripts/online_install.sh full" on that server in an interactive console. Select "<Next>/<Yes>/<OK>" whenever prompted - this console UI has no options.
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
