Laxman commented on HBASE-4791:
-------------------------------
@Matt, "zookeeper.sasl.clientconfig" is only for client context name.
Basically, in a JAAS configuration we can have multiple sections like below one.
{noformat}
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
useTicketCache=false
keyTab="/hbase/master/conf/hbase.keytab"
principal="hbase/had...@hadoop.com";
};
{noformat}
ZOOKEEPER-1373 enables the user to configure a specific section from JAAS to be
used for zookeeper and *it still requires the configuration
"java.security.auth.login.config"*. But, current jira is mainly for allowing
the JAAS can be configured via programmatically and avoid configuring via
system property. So, this requires changes on zookeeper like allowing client to
provide a config object or so...
Correct me if my understanding is wrong.
> Allow Secure Zookeeper JAAS configuration to be programmatically set (rather

> 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.
