Subject [jira] [Commented] (UIMA-6037) agent autostart should rsync its local ducc_runtime tree
Date Thu, 06 Jun 2019 13:22:00 GMT

    [ https://issues.apache.org/jira/browse/UIMA-6037?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16857642#comment-16857642
] 

Lou DeGenaro commented on UIMA-6037:
------------------------------------

The desired behavior is for autostart.py is:
 # determine what DUCC daemons should be running locally
 # if none are running locally and shared filesystem is not being used, use ducc_rsync to
synchronize local DUCC node (e.g. Agent) with head node
 # start missing DUCC processes, if any
 # DUCC Agent processes should:
 ** NOT have user DUCC privs on head node
 ** NOT have r/w privs to DB
 ** NOT use ssh (but should use DUCC broker)
