Hi [~daryn]:
I strongly agree that removing the blindly is bad for postmodern debug.
I attach the new patch in which i try to replace NPE with other exception
which can give the real reason. For UGI and offline imag related NPE, I do
not find suitable exception and they remains the same. And could you please
review the new change in the new patch.

Daryn Sharp commented on HDFS-13451:
I disagree with removing the possibility of NPEs by simply ignoring invalid
states. It will only further mask bugs. It will introduce more insanely
difficult to root cause bugs that would have never happened if the code blew up
early due to the invalid state that should be impossible.
The UGI auth method _cannot_ be PROXY w/o having a real user. The UGI is in an
illegal state that cannot be ignored.
When {{BlockInfo#getDatanode(int)}} returns null it's semantically equivalent
to ArrayIndexOutOfBoundsException – which it arguably should be. Treating this
condition as "ok" and skippable only masks bugs. The existing callers are
being bad.
The offline image change appears to simply ignore what is effectively a
corrupted image format.
