Reinstalling Monitoring Components After an Upgrade
During an upgrade from MEP 6.x to MEP 7.0.0 or MEP 7.0.1, some monitoring components do not get
updated because of an error in the fourth digit of the package version. This page provides a
workaround for the issue.
The issue (known issue ES-77) is fixed in MEP 7.1.0 and later.
This issue can occur during
manual upgrades or upgrades performed using the Installer. The affected components
can include any or all of the following:
Elasticsearch
Fluentd
Grafana
Kibana
Follow these steps to identify, remove, and reinstall the packages that were
not upgraded:
After upgrading, use one of the following commands to check the package
versions of the installed monitoring components:
OS
Command
RHEL/CentOS
yum list installed
SUSE
zypper packages --installed-only
Ubuntu
apt list --installed
Identify the packages that were not upgraded. The following table shows the
desired versions for each package for MEPs 7.0.0 and 7.0.1. For more version
information, see Component Versions for Released MEPs.

Before removing the packages that were not upgraded:
Ensure that you have backed up any configuration files and indexes as
described in Pre-Upgrade Steps for Monitoring. For
Elasticsearch in particular, you must back up the default location for
Elasticsearch index data unless you specified a non-default location
using the -ESDB parameter with
configure.sh during installation.
Export or make backup copies of any custom dashboards you configured
for Grafana or Kibana.
Manually uninstall the packages that were not upgraded by using one of the
following commands. For example, to uninstall the Elasticsearch package:
RHEL/CentOS:
yum remove mapr-elasticsearch
SUSE:
zypper remove mapr-elasticsearch
Ubuntu:
apt remove mapr-elasticsearch --purge
Install the desired packages for MEP 7.0.0 or MEP 7.0.1 using one of the
following methods:
