I did some further thinking on this.
Doen anyone know if the camel-hdfs feature includes all necessary
dependencies e.g. hadoop-common-xx.jar? or must these be added to the Karaf
classpath to get things to work?
While we're on the subject, does anyone know how to add a library that is
not an OSGi bundle to the Karaf classpath? I tried dropping the
aforementioned hadoop-common-xx.jar into the lib/endorsed directory. I then
restarted Karaf. I got a ClassNotfoundException message on the console.
Now this class is indeed included in the jar file. What gives?
If I remove the jar then restart the error does not occur.
log4j:ERROR Could not instantiate class
