Subject ReadOnly WebHDFS
Date Fri, 06 Nov 2015 11:02:25 GMT
Hi,

We run a cluster with security set to simple.
Also, to some users, we had provided http access to HDFS via HttpFS
gateways.
However, this is not scaling and we are suffering from HttpFs gateway
choking problem. So, we wanted to enable WebHDFS directly on hadoop. But
this brings in the problem of security. Any user can simply delete
anything. And, we can't enable immediately enable kerberos security in
production.

How about introducing a configuration to make WebHDFS readonly?
We patched this in our clusters cleanly and its working.

Please revert with your comments if its a good idea to push this to hadoop.
If yes, I will create a jira and submit patch.

Laxman
