在Mac OS X上，我使用以下命令从源代码编译Spark:
jacek:~/oss/spark
$ SPARK_HADOOP_VERSION=2.4.0 SPARK_YARN=true SPARK_HIVE=true SPARK_GANGLIA_LGPL=true xsbt
...
[info] Set current project to root (in build file:/Users/jacek/oss/spark/)

[info] Done packaging.

当我启动./bin/spark-shell时，我注意到以下警告消息:
警告原生hadoop库:无法为您的平台……在合适的地方使用内置java类
可能是什么问题?

Apache Hadoop中支持的原生库平台指南文档如下:
本机hadoop库仅支持*nix平台。的库不能在Cygwin或Mac OS X平台上工作。
原生hadoop库主要用于GNU/Linus平台和已在这些发行版上测试:
- RHEL4/Fedora
Ubuntu Gentoo在上述所有发行版中，32/64位原生hadoop库将与相应的32/64位jvm一起工作。
在Mac OS X上应该忽略WARN消息，因为本机库不存在于该平台。
根据我的经验，如果您将cd放入/sparkDir/conf并将spark-env.sh.template重命名为spark-env.sh，然后设置JAVA_OPTS和hadoop_DIR，它就可以工作了。
您还必须编辑/etc/profile行:
export LD_LIBRARY_PATH=$HADOOP_HOME/lib/native/:$LD_LIBRARY_PATH
