# Cancel steps when you submit work to an Amazon EMR cluster
<a name="emr-cancel-steps"></a>

You can cancel pending and running steps from the AWS Management Console, the AWS CLI, or the Amazon EMR, when you submit work to your cluster. API.

------
#### [ Console ]

**To cancel steps with the console**

1. Sign in to the AWS Management Console, and open the Amazon EMR console at [https://console.aws.amazon.com/emr](https://console.aws.amazon.com/emr).

1. Under **EMR on EC2** in the left navigation pane, choose **Clusters**, and then select the cluster that you want to update.

1. On the **Steps** tab on the cluster details page, select the check box next to the step you wants to cancel. Choose the **Actions** dropdown menu and then select **Cancel steps**.

1. In the **Cancel the step** dialog, choose to either cancel the step and wait for it to exit, or cancel the step and force it to exit. Then choose **Confirm**.

1. The status of the steps in the **Steps** table changes to `CANCELLED`.

#### [ CLI ]

**To cancel with using the AWS CLI**
+ Use the `aws emr cancel-steps` command, specifying the cluster and steps to cancel. The following example demonstrates an AWS CLI command to cancel two steps.

  ```
  aws emr cancel-steps --cluster-id j-2QUAXXXXXXXXX \
  --step-ids s-3M8DXXXXXXXXX s-3M8DXXXXXXXXX \
  --step-cancellation-option SEND_INTERRUPT
  ```

With Amazon EMR version 5.28.0, you can choose one of the two following cancellation options for `StepCancellationOption` parameter when canceling steps. 
+ `SEND_INTERRUPT`– This is the default option. When a step cancellation request is received, EMR sends a `SIGTERM` signal to the step. add a `SIGTERM` signal handler to your step logic to catch this signal and terminate descendant step processes or wait for them to complete.
+ `TERMINATE_PROCESS` – When this option is selected, EMR sends a `SIGKILL` signal to the step and all its descendant processes which terminates them immediately.

------

**Considerations for canceling steps**
+ Canceling a running or pending step removes that step from the active step count.
+ Canceling a running step does not allow a pending step to start running, assuming no change to `stepConcurrencyLevel`.
+ Canceling a running step does not trigger the step `ActionOnFailure`.
+ For EMR 5.32.0 and later, `SEND_INTERRUPT StepCancellationOption` sends a `SIGTERM` signal to the step child process. You should watch for this signal and do a cleanup and shutdown gracefully. The `TERMINATE_PROCESS StepCancellationOption` sends a `SIGKILL` signal to the step child process and all of its descendant processes; however, asynchronous processes are not affected.
