Apache Spark provides a set of user interfaces (UI) that allow you to monitor and troubleshoot the issues in a Spark cluster. This section helps you to understand the information accessed from these UIs.
The following are the default ports of the main UIs available for Spark. These ports can be configured in the <DAS_HOME>/repository/conf/analytics/spark/spark-defaults.conf file.
These ports are only available when WSO2 DAS is deployed as a Spark cluster.
| UI | Default port |
|---|---|
| Master UI** | 8081 |
| Worker UI** | 1150 |
| Application UI | 4040 |
