Answer 1

Check the HDFS Proxy Guide.

There is also Hoop which is being contributed to Hadoop by Cloudera. Currently it's targeted for the 0.24 release. But, it can be build, installed and configured manually using the instructions at the Hoop Site.

While HDFS Proxy supports only W, HOOP supports R/W to HDFS. Plan is to replace HDFS Proxy with Hoop.

While the above options are proxy based, another option is to to directly access the NameNode without a proxy. Browse the file system (http://namenode:50070/nn_browsedfscontent.jsp) and go to the file for which the URL has to be shared.

Edit: Also check WebHDFS.
