Help: run with another user, env disappear

Code:
#!/bin/sh
PATH_1=$PATH
echo "PATH_1 is " $PATH_1
function user_func (){
  whoami
  export PATH=$PATH_1:/usr/local/bin
  echo "PATH is" $PATH
  exit
}
export -f user_func
su -m hadoop -c 'user_func'

from out put, PATH is not set with PATH_1 append ( it's not another user to run the script, it's the user "hadoop" inside the script to run the function 'user_func' )
Code:
PATH_1 is  /usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin
hadoop
PATH is /bin:/usr/bin
