---------------------------
Attachment: 11083-v1.txt
> ExportSnapshot should provide capability to limit bandwidth consumption
> -----------------------------------------------------------------------
>
> Key: HBASE-11083
> URL: https://issues.apache.org/jira/browse/HBASE-11083
> Project: HBase
> Issue Type: Improvement
> Components: snapshots
> Reporter: Ted Yu
> Assignee: Ted Yu
> Attachments: 11083-v1.txt
>
>
> This capability was first brought up in this thread:
> http://search-hadoop.com/m/DHED4Td8Xb1
> The rewritten distcp already provides this capability.
> See MAPREDUCE-2765
> distcp implementation utilizes ThrottledInputStream which provides bandwidth
> throttling on a specified InputStream.
> As a first step, we can
> * add an option to ExportSnapshot which expresses bandwidth per map in MB
> * utilize ThrottledInputStream in ExportSnapshot#ExportMapper#copyFile().
