Examples of org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenSelector.selectToken()

org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenSelector.selectToken()
Select the delegation token for hdfs. The port will be rewritten to the port of hdfs.service.host_$nnAddr, or the default rpc namenode port. This method should only be called by non-hdfs filesystems that do not use the rpc port to acquire tokens. Ex. webhdfs, hftp @param nnUri of the remote namenode @param tokens as a collection @param conf hadoop configuration @return Token

    // check that the token selected for one of the physical IPC addresses
    // matches the one we received
    for (InetSocketAddress addr : nnAddrs) {
      Text ipcDtService = SecurityUtil.buildTokenService(addr);
      Token<DelegationTokenIdentifier> token2 =
          dts.selectToken(ipcDtService, ugi.getTokens());
      assertNotNull(token2);
      assertArrayEquals(token.getIdentifier(), token2.getIdentifier());
      assertArrayEquals(token.getPassword(), token2.getPassword());
    }
