Installation and Upgrade Notes (MapR 6.0.1)

This page describes considerations for upgrading to Map 6.0.1.

If you are upgrading from MapR 4.x or 5.x, be sure to review Installation and Upgrade Notes (MapR 6.0.0) first.

Upgrading to MapR 6.0.1 Using the MapR Installer

Note these considerations for upgrading to MapR 6.0.1 using the MapR Installer:

MapR Installer 1.9.0 Before upgrading, update the MapR Installer to version 1.9.0 or later. Only MapR Installer 1.9.0 or later can be used with MapR 6.0.1 and MEP 5.0.0.
MapR 6.0.1 and MEP 5.0.0 MapR 6.0.1 requires MEP 5.0.0. MEP 4.x can coexist with MapR 6.0.1 only temporarily in the context of an upgrade.
Version Upgrade Upgrading to MapR 6.0.1 using the MapR Installer requires you to perform a version upgrade. Even if the cluster to be upgraded is running MapR 6.0.0, you cannot complete the upgrade by doing a maintenance update. A maintenance update assumes that the MEP version will not change, but upgrading from MapR 6.0.0 to MapR 6.0.1 requires upgrading the MEP version from 4.x to 5.0.0 or later.
Changes to Auto-Provisioning Templates MapR 6.0.1 introduces new and changed auto-provisioning templates. See the Installer 1.9 information in Auto-Provisioning Templates.
Renamed Services The following services are renamed in MapR Installer 1.9.0:

Old Name → New Name

OJAI Query Service → OJAI Distributed Query Service

HBase/MapR-DB Common → MapR DataBase

Enhanced Security for Passwords To support enhanced security, the MapR Installer:
  • Implements password verification for every password entered.
  • Requests password information for certain MapR Monitoring components if the security mode requires passwords. For more information, see the MapR Installer operational changes in Operational Changes (MapR 6.0.1).
MapR DataBase Service and Gateways Installing the MapR DataBase service automatically triggers installation of the gateway package, the MapR Data Access Gateway, and some streams components, depending on the auto-provisioning template you choose.
Querying Using Secondary Indexes New options are available for configuring the cluster to query secondary indexes. See Preparing Clusters for Querying using Secondary Indexes on JSON Tables.

Upgrading to MapR 6.0.1 Manually

Note these considerations for upgrading to MapR 6.0.1 using manual steps:

MapR 6.0.1 and MEP 5.0.0 MapR 6.0.1 requires MEP 5.0.0. MEP 4.x can coexist with MapR 6.0.1 only temporarily in the context of an upgrade.
Querying Using Secondary Indexes New options are available for configuring the cluster to query secondary indexes. See Preparing Clusters for Querying using Secondary Indexes on JSON Tables.
MapR DataBase Service and Gateways If you install the mapr-hbase-common package, consider installing these additional packages that are installed automatically when mapr-hbase-common is installed by the MapR Installer:
  • mapr-data-access-gateway
  • mapr-gateway
Installing Metrics and Logging Components The manual steps for installing MapR Monitoring metrics and logging components now include steps for specifying passwords for Grafana and Elasticsearch:
