libhdfs3

*  Build Requirements

  To build libhdfs3, the following libraries are needed.

  * cmake (2.8+) from http://www.cmake.org/

  * google protocol buffers from http://code.google.com/p/protobuf/

  * kerberos from http://web.mit.edu/kerberos/

  * libuuid from http://sourceforge.net/projects/libuuid/

  * libgsasl from http://www.gnu.org/software/gsasl/

  To run code coverage tests, the following tools are needed.

  * gcov (included in gcc distribution)

  * lcov (tested on 1.9)            http://ltp.sourceforge.net/coverage/lcov.php

* Unit Tests

    You can run unit tests with the command:

+---+
  make unittest
+---+

    libhdfs3 also includes a suite of functional tests.  To run these tests,
    you will need a running hdfs instance to test against.  Then, you will need
    to create a function test configuration file in
    <<<$LIBHDFS3_HOME/test/data/function-test.xml>>>.  See
    <<<$LIBHDFS3_HOME/test/data/function-test.xml.example>>> for an example
    configuration file.

    You can run functional tests with:

+---+
  make functiontest
+---+
    
    You can run code coverage tests with:

+---+
  make ShowCoverage
+---+

    The code coverage result will be placed at <<<$BUILD_DIR/CodeCoverageReport/index.html>>>.
