Managing Services

Updated at: Mar 25, 2021 GMT+08:00

You can perform the following operations on MRS:

  • Start the service in the Stopped, Stop Failed, or Failed to Start state to use the service.
  • Stop the services or stop abnormal services.
  • Restart abnormal services or configure expired services to restore or enable the services.


You have synchronized IAM users (on the Dashboard tab page, click Click to synchronize on the right side of IAM User Sync to synchronize IAM users).

Figure 1 Synchronizing IAM users (using MRS 2.1.0 as an example)


  1. On the MRS cluster details page, click Components.

    For versions earlier than MRS 1.8.10, see Managing Services.

  2. Locate the row that contains the target service, Start, Stop, and Restart to start, stop, or restart the service.

    Services are interrelated. If a service is started, stopped, and restarted, services dependent on it will be affected.

    The services will be affected in the following ways:

    • If a service is to be started, the lower-layer services dependent on it must be started first.
    • If a service is stopped, the upper-layer services dependent on it are unavailable.
    • If a service is restarted, the running upper-layer services dependent on it must be restarted.
