Scenario: Apache Tez application hangs in Azure HDInsight

  • Article

This article describes troubleshooting steps and possible resolutions for issues when interacting with Azure HDInsight clusters.

Issue

After submitting Apache Hive job, from Tez view the job status is "Running", but doesn't appear to make any progress

Cause

Too many jobs submitted; long Yarn queue.

Resolution

Scale up the cluster, or just wait till the Yarn queue is drained.

By default yarn.scheduler.capacity.maximum-applications controls the maximum number of applications that are running or pending, and it defaults to 10000.
