I think you can do something like this. I don't have impala-shell, so
I wasn't able to test this. It worked using another executable though.
This is pretty bare bones, no sessions, etc.

(require 'org)
(require 'ob)

(defun org-babel-execute:impala (body params)
  (let* ((code (org-babel-expand-body:generic body params))
	 (src-dir (make-temp-file "ob-impala-" t))
         (src-file (f-join src-dir (concat (file-name-nondirectory src-dir) ".imp"))))

    (with-temp-file src-file
      (insert code))

    ;; Compile step
    (org-babel-eval
     (format "impala-shell %s" src-file)
     "")))


;;;###autoload
(eval-after-load 'org
  '(add-to-list 'org-src-lang-modes '("impala" . impala)))


(add-to-list 'org-src-lang-modes '("impala" . sql))
