Akira AJISAKA updated HDFS-6262:
--------------------------------
Release Note: HDFS's rename(src, dst) throws FileNotFoundException instead
of returning false if the source of the rename does not exist.
Hadoop Flags: Incompatible change
> 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
> Assignee: Akira AJISAKA
> Attachments: HDFS-6262.patch
>
>
> 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
