Subject [jira] [Commented] (HADOOP-7661) FileSystem.getCanonicalServiceName throws NPE for any file system uri that doesn't have an authority.
Date Wed, 21 Sep 2011 18:45:08 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13109769#comment-13109769
] 

Suresh Srinivas commented on HADOOP-7661:
-----------------------------------------

+1 for the patch. If there are no unit tests for this functionality, we should add one.

Can you please create a trunk jira to annotate this method as private and stable. Stable since
changing this would be backward incompatible.
