Rebooting a broker for an Amazon MSK cluster

Use this Amazon MSK operation when you want to reboot a broker for your MSK cluster. To reboot a broker for a cluster, make sure that the cluster in the ACTIVE state.

The Amazon MSK service may reboot the brokers for your MSK cluster during system maintenance, such as patching or version upgrades. Rebooting a broker manually lets you test resilience of your Kafka clients to determine how they respond to system maintenance.

Rebooting a broker using the AWS Management Console

1. Open the Amazon MSK console at https://console.aws.amazon.com/msk/.

2. Choose the MSK cluster whose broker you want to reboot.

3. Scroll down to the Broker details section, and choose the broker you want to reboot.

4. Choose the Reboot broker button.

Rebooting a broker using the AWS CLI

1. Run the following command, replacing ClusterArn with the Amazon Resource Name (ARN) that you obtained when you created your cluster, and the BrokerId with the ID of the broker that you want to reboot.

   Note

   The reboot-broker operation only supports rebooting one broker at a time.

   If you don't have the ARN for your cluster, you can find it by listing all clusters. For more information, see Listing Amazon MSK clusters.

   If you don't have the broker IDs for your cluster, you can find them by listing the broker nodes. For more information, see list-nodes.

   aws kafka reboot-broker --cluster-arn ClusterArn --broker-ids BrokerId

   The output of this reboot-broker operation looks like the following JSON.

   {
       
       "ClusterArn": "arn:aws:kafka:us-east-1:012345678012:cluster/exampleClusterName/abcdefab-1234-abcd-5678-cdef0123ab01-2",
       "ClusterOperationArn": "arn:aws:kafka:us-east-1:012345678012:cluster-operation/exampleClusterName/abcdefab-1234-abcd-5678-cdef0123ab01-2/0123abcd-abcd-4f7f-1234-9876543210ef"
   }

2. To get the result of the reboot-broker operation, run the following command, replacing ClusterOperationArn with the ARN that you obtained in the output of the reboot-broker command.

   aws kafka describe-cluster-operation --cluster-operation-arn ClusterOperationArn

   The output of this describe-cluster-operation command looks like the following JSON example.

   {
       "ClusterOperationInfo": {
           "ClientRequestId": "c0b7af47-8591-45b5-9c0c-909a1a2c99ea",
           "ClusterArn": "arn:aws:kafka:us-east-1:012345678012:cluster/exampleClusterName/abcdefab-1234-abcd-5678-cdef0123ab01-2",
           "CreationTime": "2019-09-25T23:48:04.794Z",
           "OperationArn": "arn:aws:kafka:us-east-1:012345678012:cluster-operation/exampleClusterName/abcdefab-1234-abcd-5678-cdef0123ab01-2/0123abcd-abcd-4f7f-1234-9876543210ef",
           "OperationState": "REBOOT_IN_PROGRESS",
           "OperationType": "REBOOT_NODE",
           "SourceClusterInfo": {},
           "TargetClusterInfo": {}
       }
   }

When the reboot operation is complete, the OperationState is REBOOT_COMPLETE.
