Zhe Zhang commented on HDFS-8199:
---------------------------------

[~zhangyongxyz] Thanks for the work. If I understand correctly, the purpose of 
this JIRA is to create a system-level (real cluster) testing plan instead of 
unit testing. Usually under system testing JIRAs, test setups and results are 
discussed instead of a code patch.

In an offline discussion [~walter.k.su] mentioned some interesting results of 
creating a 100GB striped file. That test sounds very relevant to this JIRA. 
Walter, it'd be great if you could share the results and insights here.
