Required Settings
Be sure you have set the following in db.properties:
db.ha.enabled: set to true if you want to use the replication feature.
Example: db.ha.enabled=true
db.cloud.slaves: set to a comma-delimited set of slave hosts for the cloud
database. This is the list of nodes set up with replication. The master node is
not in the list, since it is already mentioned elsewhere in the properties file.
Example: db.cloud.slaves=node2,node3,node4
db.usage.slaves: set to a comma-delimited set of slave hosts for the usage
database. This is the list of nodes set up with replication. The master node is
not in the list, since it is already mentioned elsewhere in the properties file.
Example: db.usage.slaves=node2,node3,node4
按照以上操作后，出现如下错误，不知为何?
PS：DB的主从已OK
