Andrew Purtell commented on HBASE-1980:
---------------------------------------
Amazon announced today a new capability for optionally starting up instances
backed by EBS storage:

*Amazon EC2 Boot from Amazon EBS*
Amazon EC2 has also announced the ability to boot instances directly from
Amazon EBS snapshots, providing significantly increased flexibility in how
customers can manage their instances. You can still save an Amazon Machine
Image (AMI) in an Amazon S3 bucket and boot it from the local instance store,
but you can now also choose to save AMIs as Amazon EBS snapshots and boot
directly from an Amazon EBS volume. When an instance is booted from an Amazon
EBS snapshot, the root partition of the instance is created on an Amazon EBS
volume. Instances booted from Amazon EBS volumes can be stopped and later
restarted, preserving any of the state that is saved to your volume and
allowing you to modify some properties of your instances while it is stopped.
For example, you can change your instance size or update the kernel it is
using, or attach your root partition to a different running instance, making it
easier to do debugging when you are creating new boot images. When booting from
an Amazon EBS volume, AMIs and root partitions are no longer limited to 10GB,
but can be up to 1TB in size, enabling significantly more complex images.
Additionally, you are not charged for stopped instance hours and you will only
incur charges for your Amazon EBS volumes while your instance is stopped,
allowing you to reduce your Amazon EC2 costs when you do not need your
instances running. Customers can now use a newly launched API that makes it
easy to bundle images without using the command line tools, and can also take
advantage of the fact that the content of an Amazon EBS volume is available to
the instance immediately on volume creation which can lead to much faster
instance boot times.

Could be one way to accomplish this.

> Key: HBASE-1980
> URL: https://issues.apache.org/jira/browse/HBASE-1980
> Project: Hadoop HBase
> Issue Type: Sub-task
> Reporter: Andrew Purtell
> Assignee: Andrew Purtell
> Priority: Minor
> Fix For: 0.20.3, 0.21.0
>
>
> Tweak HBase EC2 scripts to provide an option for backing HDFS with EBS
> volumes instead of plain instance storage.
> Accept a list of EBS volume identifiers to assign to datanodes or dynamically
> create them on behalf of the user. Use ZK to coordinate volume mounts on the
> datanodes.
> Will also require terminate-hbase-cluster to do a clean HBase shutdown if EBS
> volumes are used rather than just ec2-terminate-instance. Presumably this
> option would be used to persist data across cluster instances.
