-----------------------------------
Summary: Workflow xml configuration parser cannot deal with
namespace qualifier
Key: OOZIE-2400
URL: https://issues.apache.org/jira/browse/OOZIE-2400
Project: Oozie
Issue Type: Bug
Components: core
Affects Versions: 4.2.0, 4.1.0, trunk, 4.3.0
Environment: Oracle Linux 6.6, Oozie 4.1.0, Cloudera CDH 5.4.2
Reporter: Roman Krüger
Priority: Critical
Fix For: trunk, 4.3.0, 4.2.0, 4.1.0
When running a java action and a spark action via an oozie workflow xml, the
xml contains multiple namespaces (e.g. uri:oozie:workflow:0.5 and
uri:oozie:spark-action:0.1).
Thus the elements need to be prefixed by the namespace qualifier. But when
running this workflow, the configuration parser throws the exception "*JA009:
bad conf file: top-level element not <configuration>*".
The bug is located in class org.apache.oozie.util.XConfiguration in methods
"parseDocument(Document doc)" and "processNodes(Element root)". The xml tags
here are retrieved via "getTagName" and compared against prefix-less strings
(like "configuration"). This fails if the tag contains a namespace qualifier
and there is no workaround!
Here is an easy fix for this. All calls of "getTagName()" in these 2 methods
can be replaced by "getLocalName()".
