How to list YARN applications

Listing YARN applications shows which jobs are submitted, accepted, running, finished, failed, or killed. It is the first check for scheduler pressure, missing jobs, and application IDs needed by log or kill commands.

Use state filters to keep the list focused. A default list often shows active states, while historical investigations usually need FINISHED, FAILED, or KILLED filters.

Run the command from a Hadoop client configured for the correct ResourceManager or HA nameservice. The same user may see a different cluster if the client configuration points elsewhere.

1. List current active applications.

   $ yarn application -list
   Total number of applications (application-types: [] and states: [SUBMITTED, ACCEPTED, RUNNING]):1
   Application-Id                  Application-Name User  Queue    State
   application_1720000000000_0042  daily-etl        alice analytics RUNNING

2. Filter the list to running applications.

   $ yarn application -list -appStates RUNNING
   Total number of applications (application-types: [] and states: [RUNNING]):1
   Application-Id                  Application-Name User  Queue    State
   application_1720000000000_0042  daily-etl        alice analytics RUNNING

3. Filter by application type when the cluster runs several engines.

   $ yarn application -list -appTypes MAPREDUCE -appStates FINISHED
   Total number of applications (application-types: [MAPREDUCE] and states: [FINISHED]):1
   Application-Id                  Application-Name User  Queue    State     Final-State
   application_1720000000000_0038  QuasiMonteCarlo  alice default  FINISHED  SUCCEEDED

4. Inspect one application from the list.

   $ yarn application -status application_1720000000000_0042
   Application-Id : application_1720000000000_0042
   Application-Name : daily-etl
   State : RUNNING
   Final-State : UNDEFINED

5. Use the application ID for logs or termination.

   $ yarn logs -applicationId application_1720000000000_0042
   Container: container_1720000000000_0042_01_000001 on worker01.example.net:8041
   LogAggregationType: AGGREGATED
