GAO Rui commented on HDFS-8650:
-------------------------------
Hi [~walter.k.su], please do not be sorry. I walked through the code and read
the discussion of EC writing part in HDFS-9040. I learned a lot during the
process of investigating {{StripedDataStreamer}} :)
For writing a EC file under the RS-6-3 policy, we create 9
{{StripedDataStreamer}}, and as soon as an block group been written to DN, we
reuse the 9 {{StripedDataStreamer}} to write the next block group, right? So,
in this case, the client machine will use 9 threads for each being written EC
file. If my above understanding is right, I agree to close this jira :)
