PowerScale OneFS HDFS Configuration Guide

Configure HDFS service settings (Web UI)

Configure HDFS service settings in each access zone using the OneFS web administration interface.

1. Click Protocols > Hadoop (HDFS) > Settings.
2. From the Current Access Zone list, select the access zone in which you want to configure service settings.
3. From the HDFS Service Settings area, select the HDFS block size you want from the Default Block Size list.
   The HDFS block size determines how the HDFS service returns data upon read requests from Hadoop compute client.
4. Select the checksum type from the Default Checksum Type list.
   The HDFS service does not send any checksum data, regardless of the checksum type.
5. Click Save Changes.
