Kihwal Lee commented on HDFS-6264:
----------------------------------
We can start with undeprecating {{createNonRecursive()}}. The only reason it
was deprecated from the beginning was the assumption that {{FileSystem}} would
go away soon in favor of {{FileContext}}.
> Provide FileSystem#create() variant which throws exception if parent
> directory doesn't exist

> FileSystem#createNonRecursive() is deprecated.
> However, there is no DistributedFileSystem#create() implementation which
> throws exception if parent directory doesn't exist.
> This limits clients' migration away from the deprecated method.
> For HBase, IO fencing relies on the behavior of
> FileSystem#createNonRecursive().
> Variant of create() method should be added which throws exception if parent
> directory doesn't exist.
