Gopal V commented on HDFS-6581:
-------------------------------
bq. ramfs: causes applications to be aborted with OOM errors.
If ramfs ate 90% of memory, would a YARN task die or instead just get their
heaps swapped?
> Write to single replica in memory
> ---------------------------------

> Issue Type: Bug
> Components: datanode

> Per discussion with the community on HDFS-5851, we will implement writing to
> a single replica in DN memory via DataTransferProtocol.
> This avoids some of the issues with short-circuit writes, which we can
> revisit at a later time.
