Lorie created HADOOP-17540:
------------------------------
Summary: hadoop-client-runtime-3.3.0 not properly shading
javax.xml.bind
Key: HADOOP-17540
URL: https://issues.apache.org/jira/browse/HADOOP-17540
Project: Hadoop Common
Issue Type: Bug
Components: hdfs-client
Affects Versions: 3.3.0
Reporter: Lorie
In the file hadoop-client-modules/hadoop-client-runtime/pom.xml, it excludes
javax.xml.bind because it says it is part of the SE JDK. But, this is no
longer true in Java 11. So, when I try to use Guice to inject objects at start
up, I am getting the error
Error injecting constructor, java.lang.NoClassDefFoundError:
org/apache/hadoop/shaded/javax/xmlbind/ModuleUtil (wrong name:
javax/xml/bind/ModuleUtil)
|<exclusions>|
| |<!-- these APIs are a part of the SE JDK -->|
| |<exclusion>|
| |<groupId>javax.xml.bind</groupId>|
| |<artifactId>jaxb-api</artifactId>|
| |</exclusion>|
I was able to get past this by using zip to change the position of the
ModuleUtil.class inside the META-INF directory.
Before I made any changes:
jar tvf hadoop-client-runtime-3.3.0.jar | grep ModuleUtil*
META-INF/versions/9/javax/xml/bind/ModuleUtil.class
org/apache/hadoop/shaded/javax/xml/bind/ModuleUtil.class
After I modified the jar:
jar tvf hadoop-client-runtime-3.3.0.jar | grep ModuleUtil*
META-INF/versions/9/org/apache/hadoop/shaded/javax/xml/bind/ModuleUtil.class
org/apache/hadoop/shaded/javax/xml/bind/ModuleUtil.class
With the revised jar file, my code started. I don't know if that is the
correct way to fix but it works.
