stack commented on HBASE-11185:
-------------------------------

We don't need this anymore?

visitRegionStoreFiles?

It is done by verifySnapshot instead now?

Whats up w/ alll the javadoc warnings?

-  /**
+  /**©

Patch looks like nice speedup.  +1 after fixing any javadoc warnings that are yours.

> when SnapshotInfo or snapshot verification is executed against a remote path, it may
takes a while since all the code is mainly composed by sequential calls to the fs.
> This patch will parallelize all the snapshot operations using a thread pool to dispatch
requests. The size of the pool is tunable by using  "hbase.snapshot.thread.pool.max"
