Daryn Sharp commented on HDFS-4434:
-----------------------------------
bq. Note down the road we should do the split in the begining and pass the
components down to the rest of code - this is a failry invasive change and
should be done later in another jira.
BTW, this is something I did over a year ago but never finalized and submitted
the patch. It's also something I'm planning to do in the next few months to
reduce the unnecessary work and garbage littering.
