Start with the stack trace at MetaSpout.java:139 and inspect the initialization path for com.taobao.metamorphosis.utils.monitor.MonitorLog. Check how the Storm 0.10 integration loads the Metamorphosis dependencies, then reproduce the fetch for topic=test and partition=1. Done means message processing no longer produces the reported RuntimeException or NoClassDefFoundError.
