Błąd: nie można znaleźć ani załadować klasy głównej -Djava.library.path = .home.hdoop.hadoop -3.3.0.lib.native
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
