Ted Yu created HBASE-11083:
------------------------------
Summary: 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
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().
