[jira] [Created] (HDFS-3674) Add method(s) which could test for the
presence of an HDFS filesystem without authentication
Colin Patrick McCabe created HDFS-3674:
------------------------------------------
Summary: Add method(s) which could test for the presence of an HDFS filesystem without authentication
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.

-----------------------------------
Why not catch the SASL exception and consider that as success too?
