tomcat hbase jar inclusion

Question

I am trying to setup a simple hbase webapp using tomcat. To my knowledge I understand that i need to include the hbase jar, and hadoop jar in order to use hbase along with the zoopkeeper jar.

The problem is when I include the hbase jar in my maven pom, it downloads all sorts od transitive dependent jars that I dont want (e.g. jetty, servlet-api etc) because hbase itself has its own in built jetty web app that is used for monitoring. I believe this conflicts with tomcat packaging and start up that results in my having the following exception:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.28 logs.

When I comment out the hbase jar from my pom (all the dependent jars for hbase vanish too as expected), and tomcat deploys fine and I can access my rest/spring servlet.

I have tried to use exclusions to excluse hbase direct dependencies with the following:

            </exclusions>
        </dependency>

But to no avail I still have the problem.

So has does anyone have an exiting pom where they have including hbase and hadoop and somehow got tomcat to work perhaps using jersey too?

I know the above is not detailed I will add more details. I will paste the maven full pom.

thanks so much

Answer 1

HBase depends on Jersey as well, so you need to make sure you don't end up with two different versions of Jersey in your app.
