Checking the MapR Core Version
Some maintenance operations require you to know the version of the currently installed MapR release (sometimes referred to as the "MapR core version"). You can check the MapR core version easily from within the Control System or MapR Installer user interface or identify the version from your installed packages.
Checking the MapR Core Version Using the Control System
The Control System displays the MapR core version on the
Overview page:
To connect to the Control System, see Setting Up the Control System.
Checking the MapR Core Version Using the MapR Installer
If you used the MapR Installer to install the cluster, you
can view the MapR core version on the home page:
To set up the MapR Installer, see MapR Installer.
Checking the MapR Core Version Using maprcli
Another way to view the currently installed MapR core
version is to use the
maprcli dashboard info
command:cd /opt/mapr/bin
maprcli dashboard info -json

...Checking the MapR Core Version Using the Installed Packages
Another way to view the currently installed MapR core
version is to check the versions of the installed
mapr-core.x86_64
or mapr-core-internal.x86_64 packages. Use one of the following
commands to display the MapR package versions:| On CentOS / Red Hat | yum list installed |
| On SLES | zypper packages --installed-only |
| On Ubuntu | apt list --installed |
For
example:
yum list installed
Loaded plugins: fastestmirror
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
