Konstantin Shvachko commented on HDFS-955:
------------------------------------------

It is good to have the test. I ran it on current trunk. It successfully gets the expected exception, but then fails to close FSNamesystem with NPE. So yes it fails but not where you wanted it to.

> This is a continuation of a discussion from HDFS-909. The FSImage.saveFSImage function (implementing dfsadmin -saveNamespace) can corrupt the NN storage such that all current edits are lost.
