Description

HBASE-9501 added a config to provide throttling for replication. And each peer has same bandwidth up limit. In our use case, one cluster may have several peers and several slave clusters. Each slave cluster may have different scales and need different bandwidth up limit for each peer. So We add bandwidth to replication peer config and provide a shell cmd set_peer bandwidth to update the bandwidth in need. It has been used for a long time on our clusters. Any suggestions are welcomed.
