Shilun Fan commented on HADOOP-15984:
-------------------------------------
[~iwasakims] [~fanningpj] Thank you for the comments! I encountered some issues
while debugging locally because jsr and rs-api define some classes with similar
names but not identical content, resulting in conflicts. Indeed, Jersey1 and
Jersey2 cannot coexist.
{code:java}
// jersey1 need jsr311
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>
// jersey2 need rs-api 2.x
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.1.1</version>
</dependency> {code}
class loading resolution is one way to solve it, but it's quite challenging. We
can opt for a simpler solution, such as hadoop-thirdparty-jersey2, using shade
to rename the packages of the dependency jars. This approach is much simpler.
