[jira] [Created] (HDFS-3916) libwebhdfs (C client) code cleanups

Colin Patrick McCabe created HDFS-3916:
------------------------------------------

             Summary: libwebhdfs (C client) code cleanups
                 Key: HDFS-3916
                 URL: https://issues.apache.org/jira/browse/HDFS-3916
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 2.0.3-alpha
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
         Attachments: 0002-fix.patch

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.
