[jira] [Commented] (HBASE-4791) Allow Secure Zookeeper JAAS
configuration to be programmatically set (rather than only by reading JAAS
configuration file)
[ https://issues.apache.org/jira/browse/HBASE-4791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13293797#comment-13293797 ]
Laxman commented on HBASE-4791:
-------------------------------
IMO, this requires a fix in zookeeper as it expects JAAS configuration provided as a system property in ZooKeeperSaslClient. Changing that may not be so easy due to following reason.
* ZooKeeper client doesn't expect any configuration. It just needs a quorum string. So, introducing a configuration may introduce compatability issue.
I filed a similar hard-coding related issue ZOOKEEPER-1467.

> 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.
