Install Hadoop 2.7.3 via brew

brew_install_hadoop_2.7.3.sh

#!/usr/bin/env bash

BREW_PREFIX=$(brew --prefix);

# abort if already installed, else continue
if ! grep -q hadoop <(brew list); then
  # unlink broken installation attempts
  brew unlink hadoop > /dev/null 2>&1;

  # install hadoop 2.7.3
  # expect benign errors
  brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/7a4dabfc1a2acd9f01a1670fde4f0094c4fb6ffa/Formula/hadoop.rb;

  # retain backup of default configs
  cp -R ${BREW_PREFIX}/Cellar/hadoop/2.7.3/libexec/etc/hadoop ${BREW_PREFIX}/Cellar/hadoop/2.7.3/libexec/etc/hadoop_default;

  # export hadoop envs
  if [ -d "${BREW_PREFIX}/Cellar/hadoop" ]; then
    export HADOOP_VERSION="$(brew list --versions hadoop | awk '{ print $2 }')";
    export HADOOP_HOME="${BREW_PREFIX}/Cellar/hadoop/${HADOOP_VERSION}";
    export HADOOP_CONF_DIR="${HADOOP_HOME}/libexec/etc/hadoop";
  fi
else
  echo "Aborting... Hadoop installation already exists";
fi

I got the same error unfortunately.
