      Description

      The HDFS raid implementation (HDFS-503) creates a parity file for every file that is RAIDed. This puts additional burden on the memory requirements of the namenode. It will be nice if the parity files are combined together using the HadoopArchive (har) format.

      This was (HDFS-684) before, but raid migrated to MAPREDUCE.
