When you configure a Hadoop distribution to use with Data Director for Hadoop, the Hadoop software includes the Hadoop Distributed File System (HDFS). You can monitor the health and status of HDFS from the Data Director for Hadoop Web console. The HDFS page provides information about the node. It lets you browse the Hadoop filesystem, view NameNode logs, and view cluster information including live, dead, and decommissioning nodes, and NameNode storage information.

HDFS is the primary distributed storage used by Hadoop applications. A HDFS cluster consists of a NameNode that manages the file system metadata and DataNodes that store the actual data.

Create one or more Hadoop clusters.

1

Log in to the Data Director for Hadoop administrative console.

2

Click Clusters, and select the cluster name whose HDFS status you want to view.

3

Select Open HDFS Status Page from the Actions menu.

The HDFS status information displays is a new Web page.
