Steve Loughran commented on HADOOP-5254:
----------------------------------------
This is the root cause of another test failure of mine, something that tried to
load every class that namenode needed, one by one, and resources, and told me
off if they were missing.
Class.forName("org.apache.hadoop.hdfs.protocol.FSConstants") was throwing an
CNFE, but the .class file was around.
Looks like an ExceptionInInitializerError gets turned into a
ClassNotFoundException in Class.forName(), without any attempt to nest in the
underlying exception. Because that woudl be too helpful.
Caused by: java.lang.ClassNotFoundException: forName: loading of
org.apache.hadoop.hdfs.protocol.FSConstants failed, but loading it without
references succeeded. Check references.
