GAO Rui commented on HDFS-8260:
-------------------------------
Hi, [~xinwei]. You are right, this jira aims to keep tract of the writing
function of EC file. So, we should do system tests, and find bugs of EC writing
function. And, we could create new jiras focus on specific bugs we find by
implementing system tests. After, the bug was solved, we can do system test
again to keep finding other bugs, and so on.
