Zhe Zhang commented on HDFS-8319:
---------------------------------
bq. Yeah, actually stateful read shares the same logic.
I see, so {{prepareDecodeInputs}} always prepares additional data chunks as
well.
bq. For stateful read I think we are first reading the entire stripe into
buffer.
My previous comment was incorrect. We are actually reading from {{pos}} to the
end of the stripe into buffer.
Thanks Jing for the update. I'm going through 04 patch and will post the review
soon.
