Andy Isaacson commented on HDFS-3916:
-------------------------------------

{code}
+    for (;*str != '\0'; str++) {
{code}
Please put a space after the first {{;}}.

Other than that, this looks great.  Let's go ahead and get this checked in so 
other cleanups that depend on it can make progress (HDFS-3920 primarily).

I've build tested -- debian unstable amd64, needed libjansson-dev and 
libcurl4-openssl-dev packages but then it built just fine.

> Code cleanups in libwebhdfs.
> * don't duplicate exception.c, exception.h, expect.h, jni_helper.c.  We have 
> one copy of these files; we don't need 2.
> * remember to set errno in all public library functions (this is part of the 
> API)
> * fix undefined symbols (if a function is not implemented, it should return 
> ENOTSUP, but still exist)
> * don't expose private data structures in the (end-user visible) public 
> headers
> * can't re-use hdfsBuilder as hdfsFS, because the strings in hdfsBuilder are 
> not dynamically allocated.
