During post-installation configuration for Hadoop clusters, the installation of Revolution R Enterprise may fail with the output:This variable is related to the installation of a patch for a bash shell vulnerability. To work around the problem so the RRE installation can be performed:
1. Use the attached uninstall.sh script to clean up the incomplete installation of RRE. Copy the uninstall.sh script to /usr/lib64/Revo-7.3 (or the target Revo-7.3 directory), make sure it is executable, and run it as root from outside the directory.
2. Create a file /root/RREenv that contains the single line:Save this file and make it executable.
3. Edit line 213 of the Revolution R install.py script, which should be:Change that line to:4. Run the Revolution R installer script, install.py.

The error is due a failure to parse the user's environment during configuration and is typically caused by the presence of the following two-line variable/value set in the environment:Checking for Hadoop installation
