HDP 2.2 installs hdp-select automatically with the installation or upgrade of the first HDP component. If you have not already upgraded ZooKeeper, hdp-select has not been installed. |
To prevent version-specific directory issues for your scripts and updates, Hortonworks provides hdp-select, a script that symlinks directories to hdp-current and modifies paths for configuration directories.
Before you run hdp-select, you must remove one link:
rm /usr/bin/oozieRun hdp-select set all on your NameNode and all your DataNodes:
hdp-select set all 2.2.4.2-<$version>For example:
/usr/bin/hdp-select set all 2.2.4.2-2
