---------------------------------------
Summary: Online modification of enabled ReplicationPeerConfig
Key: HBASE-15507
URL: https://issues.apache.org/jira/browse/HBASE-15507
Project: HBase
Issue Type: Improvement
Components: Replication
Affects Versions: 1.2.0, 2.0.0, 1.3.0
Reporter: Geoffrey Jacoby
Assignee: Geoffrey Jacoby
It's currently possible to update the table CFs for a replication peer while
it's running, but not the peer configuration or data maps introduced as part of
custom replication endpoints in HBASE-11367.
This means that if you have a custom endpoint that depends on some
configuration parameter, you have to remove the peer and recreate it in order
to change the param. In some use cases that's not possible without risking data
loss.
HBASE-11393, which will consolidate tableCFs in the same znode as the rest of
ReplicationPeerConfig, may help here, but with or without it it still seems
like there needs to be further work to add update config/data API support to
ReplicationAdmin and a callback mechanism to notify the endpoints of config
parameter changes.
