> HADOOP-12636 catches exceptions on FS creation, but prints a stack trace @ warn every
time..this is noisy and irrelevant if the installation doesn't need connectivity to a specific
filesystem or object store.
> I propose: only printing the toString values of the exception chain @ warn; the full
stack comes out at debug.
> We could some more tuning: 
> * have a specific log for this exception, which allows installations to turn even the
warnings off.
> * add a link to a wiki page listing the dependencies of the shipped filesystems
