Symlink Directories with hdp-select
| ![[Warning]](../common/images/admon/warning.png) | Warning | 
|---|---|
| HDP-2.4.0 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, remove one link: - rm /usr/bin/oozie
- Run hdp-select set all on your NameNode and all your DataNodes: - hdp-select set all 2.3-$BUILD- For example: - /usr/bin/hdp-select set all 2.3-$BUILD
