Nanda kumar commented on HDFS-11699:

Thanks Anu for the update.
bq. we need to check both isClosed and ShouldClose functions separately ...
Got it, thanks for the explanation.

LGTM, +1 on patch v003, pending Jenkins.

> Add support for closed containers in SCM. When a container is closed, SCM needs to make
a set of decisions like which pool and which machines are expected to have this container.
SCM also needs to issue a copyContainer command to the target datanodes so that these nodes
can replicate data from the original locations.
