Examples of ClientProtocol

client.service.connection.ClientProtocol
@author Bernard , Romain
com.alibaba.wasp.client.ClientProtocol
Protocol that a wasp client and wasp server use to communicate with a wasp server.
org.apache.hadoop.hbase.client.ClientProtocol
Protocol that a HBase client uses to communicate with a region server.
org.apache.hadoop.hdfs.protocol.ClientProtocol
ClientProtocol is used by user code via {@link org.apache.hadoop.hdfs.DistributedFileSystem} class to communicate with the NameNode. User code can manipulate the directory namespace, as well as open/close file streams, etc.
org.apache.hadoop.mapreduce.protocol.ClientProtocol
Protocol that a JobClient and the central JobTracker use to communicate. The JobClient can use these methods to submit a Job for execution, and learn about the current system status.

Examples of org.apache.hadoop.hdfs.protocol.ClientProtocol

    public long renew(Token<?> token, Configuration conf) throws IOException {
      Token<DelegationTokenIdentifier> delToken = 
          (Token<DelegationTokenIdentifier>) token;
      LOG.info("Renewing " + 
               DelegationTokenIdentifier.stringifyToken(delToken));
      ClientProtocol nn = 
        DFSUtil.createRPCNamenode
           (SecurityUtil.getTokenServiceAddr(delToken),
            conf, UserGroupInformation.getCurrentUser());
      try {
        return nn.renewDelegationToken(delToken);
      } catch (RemoteException re) {
        throw re.unwrapRemoteException(InvalidToken.class, 
                                       AccessControlException.class);
      }
