Flavio Pompermaier updated FLINK-6103:
--------------------------------------
Description:
I've tried to move a directory to another on the LocalFilesystem and it doesn't
work (in my case fs is an instance of java.io.UnixFileSystem).
As for Flink-1840 (there was a PR to fix the issue -
https://github.com/apache/flink/pull/578) the problem is that
{{File.renameTo()}} is not reliable.
Indeed, the Javadoc says:
bq. Renames the file denoted by this abstract pathname. Many aspects of the
behavior of this method are inherently platform-dependent: The rename operation
might not be able to move a file from one filesystem to another, it might not
be atomic, and it might not succeed if a file with the destination abstract
pathname already exists. The return value should always be checked to make sure
that the rename operation was successful. Note that the java.nio.file.Files
class defines the move method to move or rename a file in a platform
independent manner
