Overview of Apache HDFS Integration

Apache HDFS is the Hadoop distributed file system. Ultra Explorer connects to your cluster's NameNode so you can browse and transfer files without the hdfs command line.

  • Direct connection to the NameNode (host:port)
  • Optional HDFS username
  • Copy between HDFS and object storage or local disks
