Zhe Zhang commented on HDFS-7661:
---------------------------------
Thanks for the design Rui. I haven't finished reading it. But some quick
comments below:
# Sorry I didn't get back to your above question in time. Yes I think we are
already reading the correct visible length for EC files, assuming no hflush.
# I guess we should rename this JIRA to "Support hflush/hsync"? Should also
consider merging it with HDFS-7691 ([~vinayrpet] are you still working on it?)
> Support read when a EC file is being written
