Steve Loughran commented on HBASE-11045:
----------------------------------------
{{FileSystem#createNonRecursive()}} isn't implemented by many filesystems,
using it would run the risk of hitting implementations that don't.
Is there any barrier to using a check for the parent dir existing before
calling create? That's essentially what most filesystems would end up doing
{code}
createNoRecursive(Filesystem fs, Path p) {
if (!fs.exists(p.parent()) throw FileNotFoundException(p.parent())
fs.create(p)
}
{code}
It's not atomic, but if you look closely at the source, it's not atomic in most
FS implementations anyway, including native (mkdirs() isn't atomic there).
