[jira] [Commented] (HBASE-4791) Allow Secure Zookeeper JAAS configuration to be programmatically set (rather than only by reading JAAS configuration file)

["Matteo Bertozzi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-4791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13509802#comment-13509802 ] 

Matteo Bertozzi commented on HBASE-4791:
----------------------------------------

[~saint.ack@gmail.com] good catch, "localhost" is not always right, do we have something to get the "default" localhost, or just InetAddress.getLocalHost().getHostName() is enough?

also it will be nice have this one in 0.94 too, since doesn't break the compatibility.
but we need to upgrade to zookeeper 3.4.5 (currently we're using 3.4.3)

> 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.
