Using ISA-L for EC

Intel Intelligent Storage Acceleration Library (ISA-L) is an open-source collection of optimized low-level functions used for storage applications. The library can improve EC performance when the Reed-Solomon (RS) codecs are used.

ISA-L is packaged and shipped with CDP. You can verify that it is being used by running the following command:

hadoop checknative

The command returns the libraries that the cluster uses. ISA-L should be listed as one of the enabled libraries.
