Anu Engineer commented on HDFS-12268:
-------------------------------------
[~linyiqun] / [~vagarychen] I would like to revert this patch and reapply with
the jar issue resolved. That allows us to deploy Ozone in real clusters and
test. I am going to reopen this issue and revert this patch for now. When you
have solved the packing issue we will commit this back.
Also, I think this issue was a blessing in disguise. We identified any critical
points in KSM / SCM which should log so that it becomes easier to debug issues
like that. Thanks to all for working with me online and off-line to root cause
and test this.
