----------------------------------
Summary: Add support of enabling default peer configs via
hbase-site.xml for all default replication peers.
Key: HBASE-24764
URL: https://issues.apache.org/jira/browse/HBASE-24764
Project: HBase
Issue Type: Improvement
Reporter: Ankit Jain
Assignee: Ankit Jain
Currently, if a user needs to apply some common peer configs to all the default
replication peers, the only way is to execute update_peer_config via CLI which
requires manual intervention and can be tedious in case of large deployment
fleet.
As part of this JIRA, we plan to add the support to have default replication
peer configs as part of hbase-site.xml like
hbase.replication.peer.default.config="k1=v1;k2=v2.." which can be just applied
by a rolling restart. Example below:
<property>
<name>hbase.replication.peer.default.configs</name>
<value>hbase.replication.source.custom.walentryfilters=x,y,z;hbase.rpc.protection=abc;hbase.xxx.custom_property=123</value>
</property>
This will be empty by default, but one can override to have default configs in
place.
The final peer configuration would be a merge of this default config + whatever
users override during the peer creation/update (if any).
Related Jira: https://issues.apache.org/jira/browse/HBASE-17543. HBASE-17543
added the support to add the WALEntryFilters to default endpoint via peer
configuration. By this new Jira we are extending the support to update peer
configs via hbase-site.xml.
