View and manage applications

You can monitor the status of the applications that are submitted in the IBM® watsonx.data instance.

Procedure

View details of the submitted Spark applications in watsonx.data

In the Applications tab, you can view the list of all applications that are submitted to watsonx.data. The tab also displays the details such as the application status, Spark version, creation time, start time, and finish time.
Note: Application can have one of the following statuses.
- ACCEPTED: The application is waiting for the allocation of cluster resources.
- RUNNING: The application is executing its tasks on the cluster. The driver is managing the execution, and executors are processing data.
- WAITING: The application is waiting for cluster resources to be allocated mostly when there are not enough resources (memory or cores) in the cluster to run the application.
- FINISHED: The application has completed all its tasks and terminated successfully.
- FAILED: The application encountered an issue that caused it to stop running.
- ERROR : An application in the error state may have faced issues even before execution, such as misconfiguration, driver or executor errors, missing dependencies, or runtime issues preventing it from starting.
- SUBMITTED: The application is just submitted.
- STOPPED: The application was actively running but was stopped, either intentionally or due to external factors.
Click the arrow to the left of an application ID in the result list, to view more details like Spark application ID and Application name.

Note: You can also filter the applications based on status using the Filter icon.

Stopping applications in watsonx.data

Important: You can stop only the applications that are in RUNNING state.

In the Applications tab, select the application that you want to stop.
Click the overflow menu and select Stop. The application status changes to STOPPED.
