Complete commit of prior merge. 

The previous merge accidentally only committed the hdfs project instead of common and MR
as well.

----------------------------------------------------------------------------------
Building components separately
If you are building a submodule directory, all the hadoop dependencies this
submodule has will be resolved as all other 3rd party dependencies. This is,
from the Maven cache or from a Maven repository (if not available in the cache
or the SNAPSHOT 'timed out').
An alternative is to run 'mvn install -DskipTests' from Hadoop source top
level once; and then work from the submodule. Keep in mind that SNAPSHOTs
time out after a while, using the Maven '-nsu' will stop Maven from trying
to update SNAPSHOTs from external repos.
----------------------------------------------------------------------------------
Importing projects to eclipse
When you import the project to eclipse, install hadoop-maven-plugins at first.
$ cd hadoop-maven-plugins
$ mvn install
Then, generate eclipse project files.
$ mvn eclipse:eclipse -DskipTests
At last, import to eclipse by specifying the root directory of the project via
[File] > [Import] > [Existing Projects into Workspace].

Building on OS/X
----------------------------------------------------------------------------------
Hadoop does not build on OS/X with Java 7.
see: https://issues.apache.org/jira/browse/HADOOP-9350
----------------------------------------------------------------------------------
Building on Windows
----------------------------------------------------------------------------------
Requirements:
* Windows System
* JDK 1.6
* Maven 3.0
* Windows SDK or Visual Studio 2010 Professional
* ProtocolBuffer 2.4.1+ (for MapReduce and HDFS)
* Findbugs 1.3.9 (if running findbugs)
* Unix command-line tools from GnuWin32 or Cygwin: sh, mkdir, rm, cp, tar, gzip
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)
If using Visual Studio, it must be Visual Studio 2010 Professional (not 2012).
Do not use Visual Studio Express. It does not support compiling for 64-bit,
which is problematic if running a 64-bit system. The Windows SDK is free to
download here:
http://www.microsoft.com/en-us/download/details.aspx?id=8279
----------------------------------------------------------------------------------
Building:
Keep the source code tree in a short path to avoid running into problems related
to Windows maximum path length limitation. (For example, C:\hdc).
Run builds from a Windows SDK Command Prompt. (Start, All Programs,
Microsoft Windows SDK v7.1, Windows SDK 7.1 Command Prompt.)
JAVA_HOME must be set, and the path must not contain spaces. If the full path
would contain spaces, then use the Windows short path instead.
You must set the Platform environment variable to either x64 or Win32 depending
on whether you're running a 64-bit or 32-bit system. Note that this is
case-sensitive. It must be "Platform", not "PLATFORM" or "platform".
Environment variables on Windows are usually case-insensitive, but Maven treats
them as case-sensitive. Failure to set this environment variable correctly will
cause msbuild to fail while building the native code in hadoop-common.
set Platform=x64 (when building on a 64-bit system)
set Platform=Win32 (when building on a 32-bit system)
Several tests require that the user must have the Create Symbolic Links
privilege.
All Maven goals are the same as described above with the exception that
native code is built by enabling the 'native-win' Maven profile. -Pnative-win
is enabled by default when building on Windows since the native components
are required (not optional) on Windows.
----------------------------------------------------------------------------------
Building distributions:
* Build distribution with native code : mvn package [-Pdist][-Pdocs][-Psrc][-Dtar]

@rem Environment Variables
@rem
@rem JAVA_HOME The java implementation to use. Overrides JAVA_HOME.
@rem
@rem HADOOP_CLASSPATH Extra Java CLASSPATH entries.
@rem
@rem HADOOP_USER_CLASSPATH_FIRST When defined, the HADOOP_CLASSPATH is
@rem added in the beginning of the global
@rem classpath. Can be defined, for example,
@rem by doing
@rem export HADOOP_USER_CLASSPATH_FIRST=true
@rem
@rem HADOOP_HEAPSIZE The maximum amount of heap to use, in MB.
@rem Default is 1000.
@rem
@rem HADOOP_OPTS Extra Java runtime options.
@rem
@rem HADOOP_CLIENT_OPTS when the respective command is run.
@rem HADOOP_{COMMAND}_OPTS etc HADOOP_JT_OPTS applies to JobTracker
@rem for e.g. HADOOP_CLIENT_OPTS applies to
@rem more than one command (fs, dfs, fsck,
@rem dfsadmin etc)
@rem
@rem HADOOP_CONF_DIR Alternate conf dir. Default is ${HADOOP_HOME}/conf.
@rem
@rem HADOOP_ROOT_LOGGER The root appender. Default is INFO,console
