> We'd like to implement a switch within hbase and expose as hbase shell command to flip the R/O flag on the fly without the need for restarting HBase.
> Idea is to have a ZooKeeper znode which by default has the value read from hbase-site.xml file and all HBase nodes will monitor it for changes. HBase shell will be able to change the value of znode which will be detected by RSs and enable or disable write queries accordingly.
> This change will not be reflected in hbase-site.xml, so user has to manually change config files if wants it to be persisted.
