Description

MAPREDUCE-2841 uses a direct buffer pool to pass data back and forth between native and Java code. The branch has an implementation which appears to be derived from the one in HDFS. Instead of copy-pasting, we should move the HDFS DirectBufferPool into Common so that MR can make use of it.
