Arun C Murthy commented on HADOOP-538:
--------------------------------------
IMHO src/native is par for the course since src/c++ contains librecordio and
libhdfs (libmapred in future?) which are sortof 'add-ons' to hadoop while
HADOOP-538 is 'core-hadoop' in a way. Hence we don't want to mix these up in
src/c++.
Another reason I wouldn't go down the path of src/c++/libhadoopzip because very
soon we might need src/c++/libhadooplzo (for lzo) or something similar... and
we don't want to proliferate share-objects needed for hadoop.
Given all this and the fact that we can house all of 'native' hadoop code (as
and when required) in a single 'src/native' I would go for the current scheme,
which can nicely create a single libhadoop.so for all of hadoop's native code.

> There has been more than one instance where java.util.zip's {De|In}flater
> classes perform unreliably, a simple wrapper over zlib-1.2.3 (latest stable)
> using java.nio.ByteBuffer (i.e. direct buffers) should go a long way in
> alleviating these woes.
