I tried to install hadoop-2.7.2 on Mac "OSX El Capitan" and getting error related to Native library:
$ hadoop checknative -a
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
openssl: false
For installation I used command hadoop brew install, I did all the required configuration changes but still no solution. After this I also tried to install hadoop using package available on Apache website but even there also I am facing same issue related to Native library.
