[jira] Updated: (HADOOP-5581) libhdfs does not get FileNotFoundException

     [ https://issues.apache.org/jira/browse/HADOOP-5581?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brian Bockelman updated HADOOP-5581:
------------------------------------

    Attachment: HADOOP-5581.patch

This patch causes HDFS to throw a FileNotFoundException in FSNamesystem instead of a generic IOException.

HADOOP-5579 fixes the parsing of the FileNotFoundException; with this patch, it should propagate the errno correctly.

> When trying to open a file that does not exist for read, libhdfs prints an error out along the line of "Cannot open file <filename>".
> I believe it should be throwing the FileNotFoundException instead.  This would allow us to correctly set the errno and more naturally give the errors to the C-based clients.
