Examples with ConfiguredNNAddress org.apache.hadoop.hdfs.DFSUtil.ConfiguredNNAddress used on opensource projects

Example 1 with ConfiguredNNAddress

use of org.apache.hadoop.hdfs.DFSUtil.ConfiguredNNAddress in project hadoop by apache.

the class TestGetConf method getAddressListFromTool.

   * addresses

   *      expected value is hostname:rpc-port.  If checkPort is false, the 
   *      expected is hostname only.

Example 2 with ConfiguredNNAddress

use of org.apache.hadoop.hdfs.DFSUtil.ConfiguredNNAddress in project hadoop by apache.

the class GetConf method printMap.

    StringBuilder buffer = new StringBuilder();
    List<ConfiguredNNAddress> cnns = DFSUtil.flattenAddressMap(map);
    for (ConfiguredNNAddress cnn : cnns) {

        }
        buffer.append(address.getHostName());
