Warn Util.nativeCodeLoader: Nie można załadować natywnej biblioteki hadoop
Sounds silly, but if you've copied .bashrc lines from somewhere
check that the quotation marks are like this:
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"
and not like this
export HADOOP_OPTS=”-Djava.library.path=$HADOOP_HOME/lib/native”
...took me some time
