Zesheng Wu commented on HDFS-5682:
----------------------------------
Thanks [~arpitagarwal], recently some of the our users have strong requirement
of read/write SLA on HBase, and we notice that HDFS's heterogeneous storage
feature is really interesting and helpful, thanks for your valuable work on
this:)
Last week I looked into HDFS-2832 and found that we need HDFS-5682 to be
finished before heterogeneous storage can be used, so I asked for the progress
of this issue. As you said this was deprioritized, I am wondering whether you
can give a more specific plan, and I can spend some time working on some of the
subtasks.
