Subject [jira] [Created] (HDFS-6262) HDFS doesn't raise FileNotFoundException if the source of a rename() is missing
Date Sun, 20 Apr 2014 20:55:15 GMT

------------------------------------

             Summary: HDFS doesn't raise FileNotFoundException if the source of a rename()
is missing
                 Key: HDFS-6262
                 URL: https://issues.apache.org/jira/browse/HDFS-6262
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.4.0
            Reporter: Steve Loughran


HDFS's {{rename(src, dest)}} returns false if src does not exist -all the other filesystems
raise {{FileNotFoundException}}

This behaviour is defined in {{FSDirectory.unprotectedRenameTo()}} -the attempt is logged,
but the operation then just returns false.

I propose changing the behaviour of {{DistributedFileSystem}} to be the same as that of the
others -and of {{FileContext}}, which does reject renames with nonexistent sources
