Steve Loughran commented on ZOOKEEPER-2345:
-------------------------------------------
good summary of tactics.
If you have a look at HADOOP-12426, we've a new class, KDiag, to go into Hadoop
core to do a big chunk of this diagnostics. Though not looking in the JAAS file
to extract its principal -nice idea. Network diagnostics is something we should
do too, probably initially independently.
The KDiag patch has yet to go in/get much public review —if you do hit kerberos
problems, then try and let us know how you got on. And any extra diagnostics
you can add will be most welcome.
