How to set the HADOOP_CLASSPATH for using the local filesystem with a local job runner? How to set the input and output path from local directories?

ClassNotFoundException arises for mapper and reducer classes when I try to run with the following command.

hadoop WordCount input/sample.txt output

current value is:

: hadoop classpath

/usr/local/hadoop/hadoop-3.2.1/etc/hadoop:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/common/lib/*:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/common/*:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/hdfs:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/hdfs/lib/*:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/hdfs/*:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/mapreduce/lib/*:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/mapreduce/*:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/yarn:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/yarn/lib/*:/usr/local/hadoop/hadoop-3.2.1/share/hadoop/yarn/*:/usr/local/hadoop/hadoop-3.2.1/etc/hadoop/usr/local/hadoop/hadoop-3.2.1/share/hadoop/common/*.jar

versions:
Apache hadoop-3.2.1 ,
openjdk 11.0.5.
