Description

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

[exec] /usr/bin/c++ -g -Wall -O2 -D_REENTRANT -D_FILE_OFFSET_BITS=64 -I/home/adi/w/apache-hadoop-trunk/hadoop-tools/hadoop-pipes/src/main/native/utils/api -I/home/adi/w/apache-hadoop-trunk/hadoop-tools/hadoop-pipes/src/main/native/pipes/api -I/home/adi/w/apache-hadoop-trunk/hadoop-tools/hadoop-pipes/src -o CMakeFiles/hadooppipes.dir/main/native/pipes/impl/HadoopPipes.cc.o -c /home/adi/w/apache-hadoop-trunk/hadoop-tools/hadoop-pipes/src/main/native/pipes/impl/HadoopPipes.cc

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.
