Configure Hadoop Cluster Changes

This page describes how to update the cluster configuration so that Pulse can collect Hadoop service metrics for monitoring.

The configurations include the following, based on the services:

  • Configuring HDFS, MapReduce, YARN, etc. for Pulse
  • Configuring Access Privileges for Non-HDFS users
  • Enabling JMX (Java Management Extensions) for metrics
  • Setting up ACLs (Access Control Lists)
  • Placing HooK JARs for query and event capture
  • Updating service-specific properties

Note You need to restart the Hadoop services to apply the changes.

Prepare SSL and Authentication Files for Remote JMX

Place the following files in their required directories before enabling SSL and Basic Authentication on the remote JMX port:

  • jmxremote.password
  • jmxremote.access
  • truststore.jks
  • keystore.jks

Apply Configuration by Distribution

The cluster configuration changes or updates needed vary by Hadoop distribution. Some changes apply to all Hadoop distributions.
