Sean Zhong commented on MAPREDUCE-5976:
---------------------------------------
Thanks, Manu. Looks good, +1
Changes of the new patch:
1. use system provided snappy header files, remove builtin snappy header
2. Java side delegate the codec check to a native function,
NativeRuntime.supportCompressionCodec(codecName : String)
> native-task should not fail to build if snappy is missing

> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: task

> Other native parts of Hadoop will automatically disable snappy support if
> snappy is not present and -Drequire.snappy is not passed. native-task should
> do the same. (right now, it fails to build if snappy is missing)
