Major Description
This bug prevents me from building a native Hadoop for my system.
The current build fails for me if zlib is not located the usual location(s).
I looked into ways to pass the necessary information to the Maven build. I found nothing that worked short of modifying the pom.xml of hadoop-common.
Luckily, this is easy for the project maintainers to fix – see patch below – since the build already includes the FindZLIB module for cmake (https://cmake.org/cmake/help/v3.0/module/FindZLIB.html). All that is missing is to allow maven command line parameters pass through to FindZLIB.
I suggest the following patch (works for me) that accepts two command line arguments, `zlib.lib` and `zlib.include` and passes them to cmake as ZLIB_LIBRARY and ZLIB_INCLUDE_DIR, respectively.
It would be used like this:
mvn package -Pdist,native -DskipTests -Dtar \ -Dzlib.lib=$HOME/lib/libz.so \ -Dzlib.include=$HOME/include
Here is my suggested patch:
diff -r hadoop-2.7.3-src/hadoop-common-project/hadoop-common/pom.xml hadoop-2.7.3-src-patched/hadoop-common-project/hadoop-common/pom.xml
