--------------------------------

             Summary: Trim the user config of {{dfs.ha.namenode.id}}
                 Key: HDFS-9693
                 URL: https://issues.apache.org/jira/browse/HDFS-9693
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: ha
    Affects Versions: 2.7.1
            Reporter: Tianyin Xu
            Priority: Minor


In 
{{hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/HAUtil.java}},
 we trim the config value of parameter {{dfs.ha.namenode.id}} in one place but 
not the other. 

{code}
  public static String getNameNodeId(Configuration conf, String nsId) {
    String namenodeId = conf.getTrimmed(DFS_HA_NAMENODE_ID_KEY);
    ...  
{code}

{code}
  public static List<String> getNameNodeIdOfOtherNodes(Configuration conf, 
String nsId) {
    ...
    String myNNId = conf.get(DFSConfigKeys.DFS_HA_NAMENODE_ID_KEY);
    ...
{code}
The latter one would cause problem if the user's configs contains extra space.
