I'm not familiar with Karaf so I do not know what is a "feature" in Karaf.
But hbase-client depends on many other jars, so usually you need to deploy them all, not only the hbase-client.jar and hadoop.jar. And for java programs, some people use maven-shade-plugin to pack a big jar with all dependencies in it and deploy it. Hope this could help. 2015-02-06 8:38 GMT+08:00 <yulin...@dell.com>: > Dell Customer Communication > > Hi All, > > I'm getting NoClassFound exception for /com/google/protobuf/Message > while getting connection to HTable in HBase.
