Description

It would be nice to have a method or methods in the HDFS client that could test for the presence of an HDFS filesystem without requiring authentication. For example, in fuse_dfs, there is an option called -oinitchecks which tries to test whether the configuration is correct by calling hdfsConnect immediately after fuse starts. However, this doesn't really work with Kerberos, since root is probably not kinit'ed.
