Steve Loughran commented on HDFS-6264:
--------------------------------------
If we're targeting 2.5.0 here, I wouldn't do it without actually implementing
this operation for most filesystems, because for a real FS it is going to be
more atomic than mkdirs+create; blobstores are special - which is why
HADOOP-9565 proposes a marker saying "abandon all expectations"
Most of the existing implementations of {{FileSystem.create()}} should be able
to call their internal {{createNonRecursive()}} implementation after doing the
mkdirs op
> 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, TestHLog#testFailedToCreateHLogIfParentRenamed relies on the
> behavior of FileSystem#createNonRecursive().
> Variant of create() method should be added which throws exception if parent
> directory doesn't exist.
