[jira] [Commented] (METRON-1783) Starting Metron REST Can Lead to

["Nick Allen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/METRON-1783?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16619280#comment-16619280 ] 

Nick Allen commented on METRON-1783:
------------------------------------

The client JAAS file gets deployed when any service calls {{storm_security_setup}}, which includes Parser, Enrichment, Profiler, Indexing, and the mysterious Metron Client.

The UIs and REST never triggered a deployment of the JAAS template. Seems like we starting REST should trigger the client JAAS template because it is needed.

> After kerberizing Metron using the Mpack in Ambari, if you start REST before the other Storm topologies, the Client JAAS configuration file does not get laid down.  This causes the following error in `/var/log/metron/metron-rest.log`.
