> Components: Spark Core

> Reporter: Ankur Dave

> `DirectByteBufferOutputStream#close()` calls `StorageUtils.dispose()` to free
> its direct byte buffer. This puts the object into an unspecified and
> dangerous state after being closed, and can cause unpredictable JVM crashes
> if it the object is used after close.
> We can make this safer by modifying `close()` to place the object into a
> known-closed state, and modify all methods to assert not closed.
