Spark History Server Alarm

UI Column

Spark History Server Alarm

Logged As



The Spark service on the node has stopped running.


Go to the Manage Services pane of the Node Properties View to check whether Spark History Server is running. Warden will try three times to restart the server automatically ever 30 minutes (by default). This 30 minute interval can be reconfigured using the parameter services.retryinterval.time.sec in the warden.conf file.

If warden successfully restarts Spark History Server, the alarm is cleared. If warden is unable to restart Spark History Server, contact MapR technical support.
