How to view the task list in Hadoop?

To view the Hadoop task list, you can use the following command:

1. Use the command “yarn application -list” to view all running YARN applications, including Hadoop tasks. This will display information such as application ID, application name, user, queue, and status.
2. Use the command “mapred job -list” to view all the running MapReduce jobs. This will display information such as job ID, user, queue, and status.
3. Use the command “hadoop job -list” to view all running Hadoop jobs. This will display information such as job ID, user, runtime, and status.

Please note that these commands need to be run on the command line interface of the Hadoop cluster and require appropriate permissions to view the list of tasks.
