我尝试设置hadoop并在 Ubuntu 中输入env中的所有bashrc个变量。问题是如果我在终端中执行以下操作，
hadoop checknative
我收到回复：
14/07/23 01:48:10 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Native library checking:
hadoop: false
zlib: false
snappy: false
lz4: false
bzip2: false
但如果我使用sudo
sudo hadoop/bin/hadoop checknative
我收到回复：
14/07/23 01:48:36 WARN bzip2.Bzip2Factory: Failed to load/initialize native-bzip2 library system- native, will use pure-Java version
14/07/23 01:48:36 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library

我应该怎么做才能看到没有sudo的库？我是否必须始终使用root？
