Please refer to following - Cloudera recommended settings:


Cloudera Management Services - Event ServerEntity Event Server

Default Storage Location /var/lib/cloudera-scm-eventserver/ on the host where the Event Server role is configured to run

Storage Configuration Defaults 5,000,000 events retained

Where to Control Data Retention or Minimum /Maximum


The amount of storage space the Event Server uses is influenced by configuring how many discrete events it may retain.


To configure data retention in Cloudera Manager Administration Console, select Home > Cloudera Management Service > Configuration > Event Server Group and edit the following property:

Maximum Number of Events in the Event Server Store


The maximum size of the Event Server store, in events. Once this size is exceeded, events are deleted starting with the oldest first until the size of the store is below this threshold

Sizing, Planning, and Best Practices


The Event Server is a managed Lucene index that collects relevant events that happen within your cluster, such as results of health tests, log events that are created when a log entry matches a set of rules for identifying messages of interest and makes them available for searching, filtering and additional action. You can view and filter events on the Diagnostics > Events tab of the Cloudera Manager Administration Console. You can also poll this data using the Cloudera Manager API.

You are welcome, I wont recommend changing the default location but you can give it a try.


Change the event server log location and then restart event server. Make sure it starts and runs correctly. Let me know how it goes.
