Erasure coding performance can be improved by including support for the Intel ISA-L native library as described in the Hadoop documentation -> https://hadoop.apache.org/docs/r3.3.4/hadoop-project-dist/hadoop-hdfs/HDFSErasureCoding.html#Enable_Intel_ISA-L
This following steps are required to enable ISA-L support:
- Building the ISA-L library
- Building Hadoop with ISA-L support
- Including the ISA-L native library in the Hadoop docker image
