> After HDFS-1073, there is no reason to couple the failure state of edits dirs and image
dirs. However, there is still a small amount of coupling in that image dirs are restored only
when edits are rolled. This is not problematic, and mirrors the old behavior, but we could
do better now -- eg provide an interfaces for ops to monitor and manually manage image dir
states at any point in time.
> This is targeted to be fixed _after_ HDFS-1073 is merged.
