Rolling Back a Patch
Removing a previously installed patch must be done manually. Alternatively, you can revert to a previous version of the patch by installing over a newer version. To minimize the impact of this change on your cluster, contact MapR Support for technical assistance.
Always test patch installs in a test environment before applying patches to production
environments. If a newly installed patch for a given software version delivers unexpected
behavior, you can remove the patch or install an older patch for the same MapR software
version over the current version. The latest patch version (for example, version
n
) and the previous patch version (version n-1
), are
always available on sftp.mapr.com. To log in, specify maprpatches
