Subject [jira] [Commented] (HADOOP-10221) Add a plugin to specify SaslProperties for RPC protocol based on connection properties
Date Thu, 06 Mar 2014 23:38:48 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13923255#comment-13923255
] 

Benoy Antony commented on HADOOP-10221:
---------------------------------------

Thanks for the code, [~daryn]. 
To make sure that I understood the logic correctly, the patch does the following:

* SaslPropertiesResolver is used to return the SaslProperties. 
* The default implementation is to return the list of qops read from hadoop.rpc.protection
* If needed, one can override by providing another implementation.

> HADOOP-10211 enables client and server to specify and support multiple QOP.  Some connections
needs to be restricted to a specific set of QOP based on connection properties.
> Eg. connections from client from a specific subnet needs to be encrypted (QOP=privacy)
