“Kesalahan: Tidak dapat menemukan atau memuat kelas utama -djava.library.path = .home.hdoop.hadoop-3.3.0.lib.native” Kode Jawaban

Kesalahan: Tidak dapat menemukan atau memuat kelas utama -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
