Raghu Angadi commented on HADOOP-5700:
--------------------------------------
+1 for javadoc fix.
Regd throwing a runtime exception, is it really different from NPE? Wouldn't
any runtime exception in NN indicate a bug in NN?
Can a user commad/usercode actually trigger this NPE? If yes, then it probably
should be regular error (IOException etc) rather than a runtime exception.
How did you notice this NPE?
> INode.getPathComponents throws NPE when given a non-absolute path

> If you pass a path that doesn't start with '/' to INode.getPathComponents, it
> throws a NullPointerException. Instead it should throw
