Make sure you have the correct components showing in HDFS.

  1. Go to Ambari Web UI > Services, then select HDFS.

  2. Check the Summary panel and make sure that the first three lines look like this:

    • NameNode

    • SNameNode

    • DataNodes

    You should not see any line for JournalNodes.
