Subject [jira] [Commented] (UIMA-6086) DUCC reliability should use ducc.properties to determine virtual ip address
Date Mon, 08 Jul 2019 11:59:00 GMT

    [ https://issues.apache.org/jira/browse/UIMA-6086?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16880251#comment-16880251

Lou DeGenaro commented on UIMA-6086:

revised entry in default.ducc.properties:

# The name of the node where DUCC runs.
# This property declares the node where the DUCC administrative processes run (Orchestrator,
# Resource Manager, Process Manager, Service Manager). This property is required and MUST
# configured in new installation. The installation script ducc_post_install initializes this

# property to the node the script is executed on.
# Reliable DUCC: if running reliably, then this value must resolve to the same ip address
# specified for the virtual_ipaddress in /etc/keepalived/keepalived.conf for master and
# backup nodes. To avoid nameserver glitches, consider specifying the ip address, not the
# host name. DUCC CLI and Agents employ this value to connect to the current reliable 
# DUCC head node.
ducc.head = <head-node>
