Identity & Group Configuration - Storm Streaming Server

The identification settings are used to assign a unique name to a Storm Streaming Server instance and to define the group to which it belongs. These elements are especially important when working with more than one server (for example, when creating a cluster). It is also recommended to specify the HostName if the server is accessible via an external domain or IP address.

Identity and group configuration can also be performed from the built-in Control Panel.

Sample Configuration

Below you'll find the default configuration for server identity:

config/preferences.xml - Identity block

xml

<Identity>
    <ServerName>MyStormServer</ServerName>
    <GroupName>DevGroup</GroupName>
    <HostName>localhost</HostName>
</Identity>

Field Explanation

Field	Description
`ServerName`	The common name of this server is intended to facilitate server identification. This value is also used as the server ID when configuring a cluster.
`GroupName`	The name of the group to which the server belongs. Like the ServerName, it is used in cluster configuration and can be anything.
`HostName`	This is the domain name (optionally the IP address) under which this server is accessible. For testing use "localhost", while for production/cluster configuration something like "stream04.yourdomain.com" will be better.

Verification

For verification, please check logs or output messages. You should see something like that:
