Subject [jira] [Commented] (ACCUMULO-1898) Report if security is enabled, both in master log and monitor.
Date Fri, 15 Nov 2013 19:23:21 GMT


Alex Moundalexis commented on ACCUMULO-1898:

Seems none of my customers are on 1.5.0+ yet.

Any confirmation of Accumulo attempt/success to use Kerberos would be helpful, especially
at startup.

Most of my pains in configuring Kerberos were caused by lack of information. There's currently
nothing in the monitor, logs, or anywhere else; even if it's buried in a log somewhere, status
would be good thing.

Bare minimum, there ought to be some sort of confirmation in the master's log at start-up.
Realize the implementation is vastly different in that it makes an external call to kinit,
but ideally there'd be a line when we first attempt to kinit and then log the results (good,
bad, etc).

For comparison the NN logs the following upon success:

10/10/25 17:01:46 INFO security.UserGroupInformation: 
Login successful for user hdfs/ using keytab file
