Description

The closeAll method should close all "cached" FileSystem (FileSystems present in the CACHE variable).

This can be very usefull when an access to the HDFS is needed in a webapp : when the web application context is unloaded from the container, the application should only call the closeAll method to stop DFSClients (and especially the LeaseChecker thread ).
