## What changes were proposed in this pull request? [HDDS-11120](https://issues.apache.org/jira/browse/HDDS-11120) (PR [#6911](https://github.com/apache/ozone/pull/6911)) introduced a rich rebalancing status info. This change causes a compatibility issue when an older server (without this change) is used alongside a newer client (with this change) because protobuf enum value (Type.GetContainerBalancerStatusInfo = 44) does not exist in the older server and fails with Message missing required fields: cmdType error. ``` ozone admin containerbalancer status INFO retry.RetryInvocationHandler: com.google.protobuf.ServiceException: org.apache.hadoop.ipc.RemoteException(com.google.protobuf.InvalidProtocolBufferException): Message missing required fields: cmdType at com.google.protobuf.UninitializedMessageException.asInvalidProtocolBufferException(UninitializedMessageException.java:81) at com.google.protobuf.AbstractParser.checkMessageInitialized(AbstractParser.java:71) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:89) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:95) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:49) at org.apache.hadoop.ipc.RpcWritable$ProtobufWrapper.readFrom(RpcWritable.java:125) at org.apache.hadoop.ipc.RpcWritable$Buffer.getValue(RpcWritable.java:187) at org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:525) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:1070) at org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:995) at org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:923) at java.base/java.security.AccessController.doPrivileged(AccessController.java:712) at java.base/javax.security.auth.Subject.doAs(Subject.java:439) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1910) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2905) , while invoking $Proxy18.submitRequest over nodeId=node1,nodeAddress=ccycloud-1.quasar-yvyafo.root.comops.site/10.140.178.0:9860 after 3 failover attempts.
