-== Using Amazon S3 Storage
-
-HBase is designed to be tightly coupled with HDFS, and testing of other filesystems
-has not been thorough.
-
-The following limitations have been reported:
-
-- RegionServers should be deployed in Amazon EC2 to mitigate latency and bandwidth
-limitations when accessing the filesystem, and RegionServers must remain available
-to preserve data locality.
-- S3 writes each inbound and outbound file to disk, which adds overhead to each operation.
-- The best performance is achieved when all clients and servers are in the Amazon
-cloud, rather than a heterogenous architecture.
-- You must be aware of the location of `hadoop.tmp.dir` so that the local `/tmp/`
-directory is not filled to capacity.
-- HBase has a different file usage pattern than MapReduce jobs and has been optimized for
-HDFS, rather than distant networked storage.
-- The `s3a://` protocol is strongly recommended. The `s3n://` and `s3://` protocols have serious
-limitations and do not use the Amazon AWS SDK. The `s3a://` protocol is supported
-for use with HBase if you use Hadoop 2.6.1 or higher with HBase 1.2 or higher. Hadoop
-2.6.0 is not supported with HBase at all.
-
-Configuration details for Amazon S3 and associated Amazon services such as EMR are
-out of the scope of the HBase documentation. See the
-link:https://wiki.apache.org/hadoop/AmazonS3[Hadoop Wiki entry on Amazon S3 Storage]
-and
-link:http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/emr-hbase.html[Amazon's documentation for deploying HBase in EMR].
-
-One use case that is well-suited for Amazon S3 is storing snapshots. See <<snapshots_s3>>.
