I am trying to work on HDFS to improve its performance by adding RDMA
functionality to its code. But i cannot find any sort of documentation or
help regarding this topic except some information about Socket Direct
Protocol or Allocated buffers. since RDMA is the premier protocol which is
highly preferred for Distributed File Systems , why is it not preferred in
case of HDFS or what are the factors which makes it tough. Any suggestions
or papers or ideas regarding the ways we can get some way to work on it. I
am using OFED Distribution , RDMA for this.
