Subject [jira] [Commented] (HDFS-8038) PBImageDelimitedTextWriter#getEntry output HDFS path in platform-specific format.
Date Sat, 04 Apr 2015 00:52:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14395425#comment-14395425
] 

Xiaoyu Yao commented on HDFS-8038:
----------------------------------

That's my first thought too and I do try that approach before submitting the 2nd patch. 
*Path(String, String)* cannot handle root where the parent is empty, i.e. Path("", "\"). We
could handle this by special handling root and bypass File object for other non-root file/dirs.
