I tried to installed MapR by running the command "bash ./mapr-setup.sh". First time it was successful and later when i went to the UI to continue the installation process, the password was not matching.
So I uninstalled MapR from the shell with the following command
yum remove 'mapr-installer*'
After uninstalling MapR when I tried to reinstall, it is giving the following error. Any solution for this
"No Presto metadata available for MapR Installer"
