I got new update on this issue.

I think it is caused by `(clojure-find-ns)`.
Here is my found:

I created a simple clojure project for used by all org-babel-clojure src 
blocks.
```elisp
(progn
   (find-file (expand-file-name 
"~/.emacs.d/Org-mode/ob-clojure/src/ob_clojure/core.clj"))
   (cider-jack-in))
```

I edebug the `org-babel-execute:clojure` process,

`org-babel-execute:clojure' has a step: ~(clojure-find-ns)~ .
This is from ~clojure-mode~. It will find current clojure buffer 
possible clojure namespace (even in org-mode). When I the following 
example org-mode buffer, it will return "namespace-not-found" error in 
nrepl response dict. Then src blcok has no error, not results.

```org
#+BEGIN_SRC clojure :session
(in-ns 'user-kk)
or
(ns user-kk)
#+END_SRC

#+BEGIN_SRC clojure :results output
(print "hi")
#+END_SRC
```

Here is a part of function `clojure-find-ns`:

       #+begin_src emacs-lisp
       (when (or (re-search-backward clojure-namespace-name-regex nil t)
                 ;; Or any form at all.
                 (and (goto-char (point-min))
                      (re-search-forward clojure-namespace-name-regex 
nil t)))
         (match-string-no-properties 4))
       #+end_src

So I created an PR to disable find namespace in Org-mode buffer:
