Accessing Event Logs on a Secure Cluster
If you want to view logs in secure mode, ensure that your browser is configured to use authentication with all supervisor nodes running logviewer. This process is similar to the process used to configure access to the Storm UI on a secure cluster (described in Configuring the Storm UI).
Add domains to the white list by setting
network.negotiate-auth.trusted-uris to a comma-separated list
containing one or more domain names and URLs. For example, the following steps configure
Firefox to use authentication with two nodes:
- Go to the
about:configconfiguration page. - Search for the
network.negotiate-auth.trusted-urisconfiguration option. - Double-click on the option.
- An "Enter string value" dialog box opens.
- In this box, enter the values
http://node1.example.com, http://node2.example.com. - Click OK to finish.
- Close and relaunch the browser.
If your cluster is not managed by Ambari, refer to the UI/Logviewer section of Apache Storm security documentation for additional configuration guidelines.
