编译后的so文件在/usr/lib目录下：
root@ubuntu1:/soft/lz4-r127# ls -al /usr/lib/liblz4.*
-rw-r--r-- 1 root root 90212 Mar 13 15:44 /usr/lib/liblz4.a
lrwxrwxrwx 1 root root    15 Mar 13 15:44 /usr/lib/liblz4.so -> liblz4.so.1.5.0
lrwxrwxrwx 1 root root    15 Mar 13 15:44 /usr/lib/liblz4.so.1 -> liblz4.so.1.5.0
-rwxr-xr-x 1 root root 86855 Mar 13 15:44 /usr/lib/liblz4.so.1.5.0

hadoop是2.7.3版本，里面自带有lz4自带的codec
哪位大神知道这是什么原因吗？

楼主尝试下面两个方法看是否有包hadoop-gpl-compression-0.*.0.jar，如果有的话，就删掉，再试试
或则执行下面脚本试试

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/lib

米有hadoop-gpl-compression-0.*.0.jar这个包，那个环境变量写进.profile也不行。
