Looks great! RB did show some white spaces added unnecessarily, I assume you could remove those on commit.
[rest] Filter for gzip/deflate content encoding that wraps both input and output side
Review Request #1254 - Created Nov. 25, 2010 and submitted
After HBASE-3275 the REST gateway uses Jetty's GzipFilter to will return gzip or deflate encoded content to the client if the client requested it using the appropriate Accept-Encoding header. However Jetty's GzipFilter only wraps output side processing. This patch implements a filter that also wraps input side processing, so clients can submit compressed PUT or POST bodies.
New unit test, passes.
