stack commented on HBASE-4791:
------------------------------
The two tests pass for me locally.
Calling the below with a null from MasterCommandLine will give us what
[~mbertozzi]?
+ String principalName = SecurityUtil.getServerPrincipal(principalConfig,
hostname);
Also, will it be a problem if we call the below in the regionserver constructor:
+ ZKUtil.loginClient(this.conf, "hbase.zookeeper.client.keytab.file",
+ "hbase.zookeeper.client.kerberos.principal", this.isa.getHostName());
... and then, for whatever reason, after we report for duty to the master, it
tells us use another name... See the code in handleReportForDutyResponse around
#1156?
Maybe the name the regionserver uses talking to the master is unrelated to
that used here when we are registering a principal?
FYI, you need curly braces even if only one line follows the if clause ... i.e.
the tests you do in login where you follow them by a single line w/ 'return' on
it. I can fix these on commit np.

> 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.
