1、文件压缩配置实现

首先你的Hadoop是需要编译安装的，参考博客：Hadoop源码编译
https://blog.youkuaiyun.com/greenplum_xiaofan/article/details/95466703
检查Hadoop支持的压缩格式：

[hadoop@vm01 hadoop-2.6.0-cdh5.7.0]$ pwd
/home/hadoop/source/hadoop-2.6.0-cdh5.7.0/hadoop-dist/target/hadoop-2.6.0-cdh5.7.0

[hadoop@vm01 hadoop-2.6.0-cdh5.7.0]$ ./bin/hadoop checknative
19/07/10 23:35:35 INFO bzip2.Bzip2Factory: Successfully loaded & initialized native-bzip2 library system-native
19/07/10 23:35:35 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library
Native library checking:
hadoop:  true /home/hadoop/source/hadoop-2.6.0-cdh5.7.0/hadoop-dist/target/hadoop-2.6.0-cdh5.7.0/lib/native/libhadoop.so.1.0.0
zlib:    true /lib64/libz.so.1
snappy:  true /lib64/libsnappy.so.1
lz4:     true revision:99
bzip2:   true /lib64/libbz2.so.1
openssl: true /lib64/libcrypto.so

hadoop checknative 虽然没没显示gzip、LZO压缩格式是否支持，是因为检查的是native，只要本机有gzip和LZO相关软件即可

2、修改core-site.xml参数支持压缩

<property>
    <name
