Hemanth Boyina commented on HDFS-15473:
---------------------------------------
thanks for the review [~weichiu]
{quote}We don't have a counter for total number snapshots
{quote}
numSnapshots in SnapshotManager could give the total number of snapshots
{quote}Ideally, you want to use an iterator to return partial results instead
of returning all in an array
{quote}
yes , iterator will be more beneficial here , But NN dont have list for
snapshots, so adding a TreeMap in Snapshot Manager should be fine ?
> Add listSnapshots command to list all snapshots
