我从源代码构建了Hadoop 2.7.3，一切都成功了。我正在使用预构建的Spark 2.0二进制文件，支持Hadoop 2.7。当我启动spark-shell时，我收到了这个警告。

hadoop checknative -a给了我

我是否必须为所有库获得本机构建？我检查了Hadoop构建指令，但是找不到有关构建其他库的任何信息。
或许我的Spark中有一些错过的配置。但我无法弄清楚是什么。我为Spark设置了这些环境变量：
set HADOOP_HOME=D:/hadoop-2.7.3
set HADOOP_CONF_DIR=%HADOOP_HOME%/etc/hadoop
set SPARK_HOME=D:/spark-2.0.0-bin-hadoop2.7
set HADOOP_COMMON_LIB_NATIVE_DIR=%HADOOP_HOME%/bin
set SPARK_LOCAL_IP=
