##Add to ~/.profile:


export JAVA_HOME=$(/usr/libexec/java_home)

export HIVE_AUX_JARS_PATH=/usr/local/Cellar/hadoop/3.1.1/libexec/share/hadoop/tools/lib/

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/usr/local/Cellar/hadoop/3.1.1/libexec/share/hadoop/tools/lib/*
##Note : That should work, 
# else, if that doesn't work,
# use this command to add all the jars shipped with Hadoop:
# export HADOOP_CLASSPATH=$(find /usr/local/Cellar/hadoop/3.1.1 -name '*.jar' | xargs echo | tr ' ' ':')
