Li Bo commented on HDFS-8120:
-----------------------------
I think Jing's idea is a good method to solve the problem.
I have just uploaded patch 007, changes include:(compare with patch 006)
1.fix bugs in {{TestDFSStripedOutputStream}};
2. Some unit tests will hang for several seconds when writing. This is not
observed using RS(3,2) but obvious using RS(6,3). I have fixed this problem in
patch 007(also can create a new jira for this bug).
> Erasure coding: created util class to analyze striped block groups
