Yiqun Lin commented on HDFS-11371:
----------------------------------
Hi [~andrew.wang], I found some metrics relevant EC that are added in
3.0.0-alpha2(HDFS-8411 and HDFS-11216 done for this), but they haven't been
documented yet. We can have a fix in 3.0.0-alpha3. Are you interest in taking a
quick look for this? This is a minor change.
