Hi all, I'm running with Hadoop 1.0.4 and HBase 0.94.12 bundled (OSGi) versions I built. Most issues I encountered are related to class loaders.
One of the patterns I noticed in both projects is: ClassLoader cl = Thread.currentThread().getContextClassLoader(); if(cl == null) { cl = Clazz.class.getClassLoader(); } Where Clazz is the Class containing this code. I was wondering about this choice... Why not go the other way around: ClassLoader cl = Clazz.class.getClassLoader(); if(cl == null) { cl = Thread.currentThread().getContextClassLoader(); } And in a more general note, why not always use Configuration (and let it's cl be this.getClass().getClassLoader()) to load classes ? That would surely help in integration with modularity frameworks. Thanks, Amit.
