Subject [jira] [Commented] (HBASE-4791) Allow Secure Zookeeper JAAS configuration to be programmatically set (rather than only by reading JAAS configuration file)
Date Mon, 18 Jun 2012 13:18:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13395875#comment-13395875

Laxman commented on HBASE-4791:
-------------------------------

I understand Matt. Looks good.
iiuc, your suggestion is to "ZooKeeper clients(like HBase) has to set this via Configuration.setConfiguration."

Following are points of discussion if we go with this approach.

* For every ZooKeeper client connection we need to do this Configuration.setConfiguration.
* Configuration.setConfiguration overwrites the default configuration. May cause problems,
if client application also expects this way.

> In the currently proposed fix for HBASE-2418, there must be a JAAS file specified in
    System.setProperty("java.security.auth.login.config"). 
> However, it might be preferable to construct a JAAS configuration programmatically, as
is done with secure Hadoop (see https://github.com/apache/hadoop-common/blob/a48eceb62c9b5c1a5d71ee2945d9eea2ed62527b/src/java/org/apache/hadoop/security/UserGroupInformation.java#L175).
> This would have the benefit of avoiding a usage of a system property setting, and allow
instead an HBase-local configuration setting.
