Preparing for the ECE environment

The ECE storage is required to be configured as shared storage to be used in the Hadoop environment.

Ensure that the Recommended hardware resource configuration for ECE is met and follow the IBM Spectrum Scale Erasure Code Edition documentation for installation.

Note: Ensure that the IBM Spectrum® Scale file system ACL setting is set to ALL. For more information, see HDFS and IBM Spectrum Scale file system ACL support section.

After the ECE storage is set up and configured, add the ECE storage to the Hadoop environment by using the same method as the shared storage mode. See Deploy HDP or IBM Spectrum Scale service on pre-existing IBM Spectrum Scale file system section.

Note: FPO is not supported on ECE.
