不支持bzip2

解决方案

1    按照bzip2包

yum -y install bzip2-devel

2 安装成功后  重新编译Hadoop  到Hadoop源码目录下

mvn package -Pdist,native -DskipTests -Dtar -Djavax.net.debug=all

3 编译完之后 检查 是否编译成功

strings ~/build/hadoop-2.6.0-cdh5.7.0/hadoop-dist/target/hadoop-2.6.0-cdh5.7.0/lib/native/libhadoop.so | grep initIDs

看到有bzip2信息表示成功

4  拷贝编译好的native下文件 替换

cp ~/build/hadoop-2.6.0-cdh5.7.0/hadoop-dist/target/hadoop-2.6.0-cdh5.7.0/lib/native/*  /mnt/software/hadoop-2.6.0-cdh5.7.0/lib/native/

5 然后 再次执行Hadoop checknative -a

[root@hdp1 /mnt/software/hadoop-2.6.0-cdh5.7.0/lib]#hadoop checknative -a
