> Many times, after deploy hadoop or when trouble shooting, we need to check whether native
library(along with native compression libraries) can work properly, and I just want to use
one command to check that, like this:
> hadoop org.apache.hadoop.util.NativeCodeLoader
> and it shows:
> Native library loading test:
> hadoop: false
> zlib:   false
> snappy: false
> lz4:    false
