Konstantin Boudnik commented on HADOOP-4885:
--------------------------------------------
After a bit more of investigation I have noticed (dah!) this new config
parameter {{dfs.name.dir.restore}} which triggers removed storage restoration.
fsimage flies for both (nfs'ed and non-nfs volumes) as well as secondary NN's
checkpoints have the same md5sums. So it seems that (as Hairong pointed out
elsewhere) that without HDFS-903 this features kinda works.
