--------------------------------------
Doug,
> 1. There's some debug output in bin/hadoop, an 'echo'.
Newer patch forthcoming to fix this oversight...

> build.xml.
I have attached the .so for linux built via 'ant compile-native'... we will
need to check this in for people who don't want to install the C compilation
environment as we had discussed previously. Am I missing something here?
> On second thought, the custom libs should probably go in build/native and the
> prebuilt in lib/native.
Just to clarify: you'd want the 'custom built' libhadoop.so to override the
'prebuilt' one in lib/native on 'ant package' ?
> Implement a nio's 'direct buffer' based wrapper over zlib to improve
> performance of java.util.zip.{De|In}flater as a 'custom codec'
