Pi Song commented on HADOOP-2759:
---------------------------------
This issue involves two things
- data file creation
- directory creation
I plan to add new mkdir and createFile that don't create all the parent dirs
instead of changing the old ones because I don't want to have backward
compatibility problems. Now the question is should I mark the old mkdir and
createFile as @deprecated? I still feel sometimes we need methods that ensure
parent dir creation but then if I don't it will encourage people to still use
the old ones and here comes problems like in HADOOP-2391.
I also need a new name for createFile that doesn't create parents. (For mkdir
it's easy, the old one is mkdirs and the new one is mkdir therefore like in
Java)
> creating a file in hdfs should not automatically create the parent directories

> I think it would be better if HDFS didn't automatically create directories
> for the user. In particular, in clean up code, it would be nice if deleting a
> directory couldn't be undone by mistake by a process that hasn't been killed
> yet creating a new file.
