CES HDFS support

Starting from IBM Storage Scale 5.0.4.2, CES also supports HDFS protocols. For more information, see CES HDFS in Big data and analytics support documentation.

The following features are available:

HDFS overview

CES HDFS follows the same generic installation methods and prerequisites like the other protocols. For more information about CES HDFS, see Overview and Limitations and Recommendations.

Integrated installation

The HDFS services are installed by the integrated installer together with the CES framework and the other protocols NFS, SMB, and Object.

Management command

With the mmhdfs and mmces commands, IBM Storage Scale provides a comprehensive entry point to manage all HDFS-related configuration tasks.

HDFS monitoring

The monitoring framework detects HDFS Transparency name node and data node failures. The name node triggers a failover if an unrecoverable error occurs. For more information, see the mmhealth command command, mmhdfs command command, and the mmces command command.
