Tsz Wo Nicholas Sze commented on HDFS-7661:
-------------------------------------------
It makes sense. Then, how do the readers access the data? A readers may
potentially read inconsistent data and parties, e.g. some parties generated at
p0 = 64k * 7 + 10 and some other parties generated at p1=64k*7+20.
> Support read when a EC file is being written
