Andy Isaacson created MAPREDUCE-4383:
----------------------------------------

             Summary: HadoopPipes.cc compile fails with "HadoopPipes.cc:1049:16: error: ‘sleep’
was not declared in this scope"
                 Key: MAPREDUCE-4383
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4383

Since MAPREDUCE-4267 I've seen "mvn -Pnative compile" failing with:

I believe the failure is new simply because I wasn't compiling pipes before.

The fix is pretty simple, just include unistd.h in HadoopPipes.cc.

My environment is debian unstable, amd64, g++ 4.7.0-6, openjdk-6-jdk 6b24-1.11.1-6.
