示例1: redirectURI

import org.apache.hadoop.net.NetworkTopology.InvalidTopologyException; //导入依赖的package包/类
private URI redirectURI(final NameNode namenode,
    final UserGroupInformation ugi, final DelegationParam delegation,
    final UserParam username, final DoAsParam doAsUser,
    final String path, final HttpOpParam.Op op, final long openOffset,
    final long blocksize, final String excludeDatanodes,
    final Param<?, ?>... parameters) throws URISyntaxException, IOException {
  final DatanodeInfo dn;
  try {
    dn = chooseDatanode(namenode, path, op, openOffset, blocksize,
        excludeDatanodes);
  } catch (InvalidTopologyException ite) {
    throw new IOException("Failed to find datanode, suggest to check cluster health.", ite);
  }

  final String delegationQuery;
  if (!UserGroupInformation.isSecurityEnabled()) {
    //security disabled
    delegationQuery = Param.toSortedString("&", doAsUser, username);
  } else if (delegation.getValue() != null) {
    //client has provided a token
    delegationQuery = "&" + delegation;
  } else {
    //generate a token
    final Token<? extends TokenIdentifier> t = generateDelegationToken(
        namenode, ugi, request.getUserPrincipal().getName());
    delegationQuery = "&" + new DelegationParam(t.encodeToUrlString());
  }
  final String query = op.toQueryString() + delegationQuery
      + "&" + new NamenodeAddressParam(namenode)
      + Param.toSortedString("&", parameters);
  final String uripath = WebHdfsFileSystem.PATH_PREFIX + path;

  final String scheme = request.getScheme();
  int port = "http".equals(scheme) ? dn.getInfoPort() : dn
      .getInfoSecurePort();
  final URI uri = new URI(scheme, null, dn.getHostName(), port, uripath,
      query, null);

  if (LOG.isTraceEnabled()) {
    LOG.trace("redirectURI=" + uri);
  }
  return uri;
