3.5. Problem: HDFS Smoke Test Fails

If your DataNodes are incorrectly configured, the smoke tests fail and you get this error message in the DataNode logs:


 3.5.1. Solution:

  • Make sure that reverse DNS look-up is properly configured for all nodes in your cluster.

  • Make sure you have the correct FQDNs when specifying the hosts for your cluster. Do not use IP addresses - they are not supported.

Restart the installation process.
