> Improve Snapshot Performance with Temporary Snapshot Directory when rootDir

> Project: HBase

>
> When using Apache HBase, the snapshot feature can be used to make a point in
> time recovery. To do this, HBase creates a manifest of all the files in all
> of the Regions so that those files can be referenced again when a user
> restores a snapshot. With HBase's S3 storage mode, developers can store their
> data off-cluster on Amazon S3. However, utilizing S3 as a file system is
> inefficient in some operations, namely renames. Most Hadoop ecosystem
> applications use an atomic rename as a method of committing data. However,
> with S3, a rename is a separate copy and then a delete of every file which is
> no longer atomic and, in fact, quite costly. In addition, puts and deletes on
> S3 have latency issues that traditional filesystems do not encounter when
> manipulating the region snapshots to consolidate into a single manifest. When
> HBase on S3 users have a significant amount of regions, puts, deletes, and
> renames (the final commit stage of the snapshot) become the bottleneck
> causing snapshots to take many minutes or even hours to complete.
> The purpose of this patch is to increase the overall performance of snapshots
> while utilizing HBase on S3 through the use of a temporary directory for the
> snapshots that exists on a traditional filesystem like HDFS to circumvent the
> bottlenecks.
