[jira] [Commented] (HDFS-3801) Provide a way to disable browsing of files from the web UI

    [ https://issues.apache.org/jira/browse/HDFS-3801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13508315#comment-13508315 ] 

Harsh J commented on HDFS-3801:
-------------------------------

Any comments on the patch? It provides a toggle that disables all browsable (i.e. linked/navigable) pages and carries a simple test as well.

> A few times we've had requests from users who wish to disable browsing of the filesystem in the web UI completely, while keeping other servlet functionality enabled (such as fsck, etc.). Right now, the cheap way to do this is by blocking out the DN web port (50075) from access by clients, but that also hampers HFTP transfers.
> We should instead provide a toggle config for the JSPs to use and disallow browsing if the toggle's enabled. The config can be true by default, to not change the behavior.
