On the NameNode host you will find a file something like this which has the "download_url" value defined as following:

# grep 'Download' /usr/hdp/2.6.1.0-129/hadoop-hdfs/webapps/hdfs/explorer.html
    <a id="file-info-download">Download</a>

- Just change that line as following:

<a href="">Download</a>

Example:

# grep -A 1 'Download' /usr/hdp/2.6.1.0-129/hadoop-hdfs/webapps/hdfs/explorer.html
    <!--a id="file-info-download">Download</a-->
    <a href="">Download</a>

(OR) Better
Simply remove that following line from the file (Or comment it)

<a id="file-info-download">Download</a>

NOTE: This change you will need to do on both Active NameNode and StandBy NameNode. You do not need to restart NameNodes after making this HTML change. Just refresh the browser.
