             Summary: HDFS Namenode UI: Fix browsing directories that need to be encoded
                 Key: HDFS-9877
                 URL: https://issues.apache.org/jira/browse/HDFS-9877
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Ravi Prakash
            Assignee: Ravi Prakash


When we browse a directory whose encoded path is not the same as unencoded path, *2* HTTP requests are sent (instead of 1) and the 2nd request fails.
e.g. when I browse {{/tmp/new directory}} (note the space) it gets encoded to {{/tmp/new%20directory}} and then [this|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/webapps/hdfs/explorer.js#L40] check fails:
{code}
    if(current_directory != dir) {
      browse_directory(dir);
    }{code}
