Subject [ANNOUNCE] Apache UIMA DUCC 2.2.0 released
Date Thu, 23 Feb 2017 21:20:00 GMT
The Apache UIMA team is pleased to announce the release of the Apache
UIMA-DUCC version 2.2.0.

The Unstructured Information Management Architecture (UIMA) is a component
framework supporting development, discovery, composition, and deployment of
multi-modal analytics tasked with the analysis of unstructured information.

Apache UIMA is an Apache licensed open source implementation of the UIMA
specification which is being developed by a technical committee within
OASIS, a standards organization. The implementation comprises an SDK and
tooling for composing and running analytic components written in Java and
C++, with some support for Perl, Python and TCL.

DUCC stands for Distributed UIMA Cluster Computing. DUCC is a cluster
management system providing tooling,management, and scheduling facilities
to automate the scale-out of applications written to the UIMA framework.
Core UIMA provides a generalized framework for applications that process
unstructured information such as human language, but does not provide a
scale-out mechanism. UIMA-AS provides a scale-out mechanism to distribute
UIMA pipelines over a cluster of computing resources, but does not provide
job or cluster management of the resources.
DUCC defines a formal job model that closely maps to a standard UIMA
pipeline. Around this job model DUCC provides cluster management services
to automate the scale-out of UIMA pipelines over computing clusters.


This release contains a number of improvements and bug fixes. Notable
updates in this release include:

 - Ships with the latest UIMA-AS v2.9.0 and UIMA SDK 2.9.0
 - Ships with ActiveMQ v5.14.0
 - Added support for static failover and capability to move the head node
 - Fixed DUCC OR "warm" restart issues
 - Fixed DUCC startup script to fail if the DB doesn't start
 - Fixed DUCC shutdown sequence bug which prevented agents from stopping if
Broker was shutdown first
 - Fixed Rogue process detector to detect and cleanup orphan services
 - Deprecated ducc.agent.node.metrics.sys.gid.max and replaced with
ducc.agent.rogue.process.sys.uid.max
 - Enhanced DUCC Job Driver (JD) to provide individual work item
performance breakdowns
 - Modified DUCC to restrict broker use to ducc user only
 - On process launch failure, agent supplies a reason for failure for
display in ducc mon
 - Added duplicate daemon detector to prevent starting duplicate DUCC daemon
 - Many DUCC Database improvements
 - Many DUCC webpage improvements
