hdfsCreateDirectory2()
Supported by libMapRClient for hadoop-2.x
Makes the given file and all non-existent parents into directories. Stores the size of the name container in a location that you pass a pointer into, so that you can keep track of this size. The size is in bytes.
Keeping track of the size of the name container is useful when you are creating files that are less than or equal to 64 KB. When the size of all of the such files together for one name container exceeds 64 GB, operations on the name container can become inefficient. If the size of a name container reaches 64 GB, you can switch to a new or different volume.
