Scenario: Apache Ambari Tez View loads slowly in Azure HDInsight

  • Article

This article describes troubleshooting steps and possible resolutions for issues when using Interactive Query components in Azure HDInsight clusters.

Issue

Apache Ambari Tez View may load slowly or may not load at all. When loading Ambari Tez View, you may see processes on Headnodes becoming unresponsive.

Cause

Accessing Yarn ATS APIs may sometimes have poor performance on clusters created before Oct 2017 when the cluster has large number of Hive jobs run on it.

Resolution

This is an issue that has been fixed in Oct 2017. Recreating your cluster will make it not run into this problem again.
