Jing Zhao updated HDFS-9173:
----------------------------
Comment: was deleted
(was: The main challenge now is that with hflush we can no longer infer what
data was used to compute the parity chunks, unless we "attach" additional
information to them. For Nicholas's example, even if we know we have 3 parity
chunks with length 64KB, currently we do not know if they are computed based on
the whole stripe, or based on a partial stripe (which is triggered by a hflush
call). )
