Daryn Sharp commented on HDFS-3674:
-----------------------------------
Why not catch the SASL exception and consider that as success too?
> Add method(s) which could test for the presence of an HDFS filesystem without

> Key: HDFS-3674
> URL: https://issues.apache.org/jira/browse/HDFS-3674
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs client
> Reporter: Colin Patrick McCabe
> Priority: Minor
>
> 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.
