Using the Imply Manager

The Imply Manager gives administrators a visual interface for deploying and managing Imply clusters. It is available in Imply Cloud and licensed Imply Private deployments.

The Imply Manager is where you create and configure clusters and servers, monitor your deployment, and apply version updates to the cluster, among other tasks.

The following sections provide more details on using the Imply Manager. For advanced Imply Manager operation modes, such as using direct access Pivot and crossover Pivot, see the Imply Managed documentation.

For information specifically on creating and administering Imply clusters, see Cluster management.

Accessing Master settings

The master settings contain the personal settings for the current user, account settings, and user settings, including user accounts and user roles. These settings apply across clusters in your deployment.

You access master settings from the top-right profile menu. The role configuration page, for instance, appears as follows:

For more information on adding users and roles, see Imply Manager users.

Updating software versions

The Imply Manager makes it easier to update software across a cluster.

If the cluster is running in high availability mode, you can apply a rolling update. With a rolling update, servers are updated one at a time, ensuring that servers remain running to maintain service availability while undergoing the update.

Rolling updates are not supported for clusters with more than one Imply service (master, query, data) on a single node.

If your cluster is not highly available, changing to a different version of the product or service (i.e., upgrading or downgrading) will interrupt service for your users for a few minutes. In Imply Cloud, this service downtime may take 15 to 20 minutes.

To update software:

1. Open the cluster overview page and then Setup. Notice that the current version is listed on the Setup page, with the available versions appearing in the Imply versions menu.
2. In the setup page, choose the version you want to update to from the Imply version menu. The Imply Manager gets and displays the version number of the latest releases automatically.
3. Click Apply changes.
4. Confirm the settings and apply the update.

The update status appears in the cluster overview page. At any point you can cancel the update, which causes the Manager to revert the upgrade, including the servers for which the update is complete.

Add custom user files

You can push custom user files to Imply cluster nodes by specifying them in the Setup / Advanced Config section of the manager. These files can be written to the following locations:

• User files (/opt/imply/user)
• Druid's classpath
• as a Hadoop dependency

Additionally, these files can be processed as follows:

• None
• Requires unpacking (extracts using tar -x)
• Is executable (sets chmod +x)

There are two ways to make these files available to the manager:

• Make them available via HTTP(S) and provide the URL
• Make them available to the manager locally and reference them using the manager:/// scheme

To make the files available to the manager locally, they will need to be placed in:

• the /mnt/var/user directory inside the manager container, for Imply Private on Kubernetes
• the /var/opt/imply/grove/user directory where the manager is running, for Imply Private on Linux

Once the files are available in that directory, reference them using the manager:/// scheme. As an example:

• File: /mnt/var/user/hdfs-site.xml -> Manager path: manager:///hdfs-site.xml

Lookups

The Lookups page lets you manage Druid lookups. For more information on lookups, see the Apache Druid documentation.

Experimental features

Experimental features are used to try out early access or other limited access features. Do not use except in consultation with Imply support.
