What commands are used to see all jobs running in the Hadoop cluster and kill a job in LINUX?

by

Hadoop job – list

Hadoop job – kill jobID

In Hadoop, you can use the following commands in Linux to see all jobs running in the cluster and kill a job:

  1. To see all running jobs:
    mapred job -list

    This command will provide a list of all running jobs in the Hadoop cluster.

  2. To kill a specific job:
    mapred job -kill <job-id>

    Replace <job-id> with the actual job ID of the job you want to terminate. You can find the job ID from the output of the mapred job -list command.

Note: The commands mentioned above may vary slightly depending on the Hadoop version. In more recent versions, you might also use yarn instead of mapred. For example:

  • To see all running jobs:
    yarn application -list
  • To kill a specific job:
    yarn application -kill <application-id>

Again, replace <application-id> with the actual ID of the job you want to terminate.
