Examples of org.apache.hadoop.hdfs.server.FailoverNameNodeProtocol

org.apache.hadoop.hdfs.server.FailoverNameNodeProtocol
This class implements the NamenodeProtocol such that it can work correctly across AvatarNode failovers. Currently we support this protocol only for the use case of the Balancer. Rest of the API's are left for implementation in future when we actually need them.

            Integer.parseInt(parts[1]));
        NamenodeProtocol nn = createNamenode(nnAddr, conf);
        if (failover) {
          newNamenode(nn);
        } else {
          failoverNamenode = new FailoverNameNodeProtocol(this.namenode,
              failoverHandler);
          this.namenode = failoverNamenode;
        }
        break;
      } catch (Exception e) {
