Hi,
is there a new patch suitable for hadoop-3.0.0-alpha1 ?

> For encoding and decoding buffers, currently some places use java heap ByteBuffer,  some
use direct byteBUffer, and some use java byte array.  If the coder implementation is native,
we should use direct ByteBuffer. This jira is to  revisit all encoding/decoding buffers and
improve them.
