Subject [jira] [Commented] (HDFS-3674) Add method(s) which could test for the presence of an HDFS filesystem without authentication
Date Wed, 18 Jul 2012 13:12:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3674?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13417058#comment-13417058

Daryn Sharp commented on HDFS-3674:
-----------------------------------

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

> 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.
