-----------------------------------
Summary: Exclude forked jersey-json from client artifacts and
binary distributions
Key: HBASE-30503
URL: https://issues.apache.org/jira/browse/HBASE-30503
Project: HBase
Issue Type: Bug
Components: build, dependencies, shading
Affects Versions: 2.6.7, 2.6.2
Reporter: mazhengxuan
Assignee: mazhengxuan
Hadoop 3.3.5 replaced com.sun.jersey:jersey-json with
com.github.pjfanning:jersey-json. HBase still excludes the old coordinate, so
the fork is included while jersey-core is excluded.
The shaded client contains JAX-RS service providers whose parent classes are
missing. Applications discovering these providers through ServiceLoader fail
with NoClassDefFoundError. The fork also bypasses the binary assembly's
com.sun.jersey:* exclusion.
Confirmed with these released hbase-shaded-client artifacts:
* 2.6.2-hadoop3 on JDK 8.
* 2.6.7-hadoop3 on JDK 8, 11 and 17.
To reproduce, download
[hbase-shaded-client-2.6.7-hadoop3.jar|https://repo.maven.apache.org/maven2/org/apache/hbase/hbase-shaded-client/2.6.7-hadoop3/hbase-shaded-client-2.6.7-hadoop3.jar]
and
[javax.ws.rs-api-2.1.1.jar|https://repo.maven.apache.org/maven2/javax/ws/rs/javax.ws.rs-api/2.1.1/javax.ws.rs-api-2.1.1.jar]
into the same directory, then save this as JerseySpiProbe.java:
{code:java}
import java.util.ServiceLoader;
import javax.ws.rs.ext.MessageBodyWriter;
public class JerseySpiProbe {
public static void main(String[] args) {
int count = 0;
for (MessageBodyWriter<?> provider :
ServiceLoader.load(MessageBodyWriter.class)) {
System.out.println(provider.getClass().getName());
count++;
}
System.out.println("Loaded providers: " + count);
}
}
{code}
Run:
{code:bash}
javac -cp javax.ws.rs-api-2.1.1.jar JerseySpiProbe.java
# Passes: Loaded providers: 0
java -cp .:javax.ws.rs-api-2.1.1.jar JerseySpiProbe
# Fails after adding the HBase client
java -cp .:javax.ws.rs-api-2.1.1.jar:hbase-shaded-client-2.6.7-hadoop3.jar
JerseySpiProbe
{code}
The last command fails with:
{noformat}
java.lang.NoClassDefFoundError:
org/apache/hadoop/hbase/shaded/com/sun/jersey/core/provider/jaxb/AbstractRootElementProvider
{noformat}
Adding the HBase client should not break JAX-RS provider discovery. The
dependency and assembly exclusions should also cover the forked coordinate.
