> Recently, native ISA-L library support is added into HDFS erasure code RS codec.  With
ISA-L, the performance of erasure code RS encode/decode will be significantly improved. This
task is to add the deploy process into the HDFS Erasure Code Document, make it easy for HDFS
user to use ISA-L enabled erasure code policy.
