Installation and Upgrade Notes (MapR 6.1.0)

CAUTION New installations of MapR 6.1.0 are no longer recommended. Because of a known issue with MapR 6.1.0, HPE recommends installing MapR 6.1.1 or MapR 6.2.0 for new installations. The MapR Installer no longer supports installing MapR 6.1.0 and automatically installs MapR 6.1.1. Installation and upgrade considerations can be found in the support advisory announcing release 6.1.1. See Announcement of HPE Ezmeral Data Fabric maintenance release 6.1.1 to address 6.1.0 critical defects.

Upgrading to MapR 6.1.0 also is no longer recommended. If you need to upgrade to MapR 6.1.x, upgrade to MapR 6.1.1. See Installation and Upgrade Notes (MapR 6.1.1).

If your cluster is currently installed with MapR 6.1.0, HPE recommends that you install the latest 6.1.0 patch. See Downloading a Patch.
