Yi Liu commented on HDFS-7348:
------------------------------
Thanks Zhe and Bo for further discussion.
I will rebase the patch, and make buffer size configurable and add decode part
as Zhe's suggestion.
For sequential vs. parallel reading, I will file a follow-on and target in
phase2. For local read and local write, you guys can do them as follow-on in
your JIRAs and target to Phase2.
