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 be
# 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>
> DUCC reliability should use ducc.properties to determine virtual ip address
