Overview
The Hadoop Common source code resides in the Apache Subversion (SVN) repository. The command-line SVN client can be obtained here. The TortoiseSVN GUI client for Windows can be obtained here. There are also SVN plugins available for both Eclipse and IntelliJ IDEA.
Web Access (read-only)
The source code can be browsed via the Web at http://svn.apache.org/viewcvs.cgi/hadoop/common/trunk/hadoop-common-project. No SVN client software is required.
Anonymous Access (read-only)
The SVN URL for anonymous users is http://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-common-project. Instructions for anonymous SVN access are here.
Committer Access (read-write)
The SVN URL for committers is https://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-common-project. Instructions for committer SVN access are here.
Git mirror
Read-only git mirrors are available at http://git.apache.org/
Committer Access (read-write) can be enabled via the git svn commands.

Anonymous access
The source can be checked out anonymously from SVN with this command:
$ svn checkout http://svn.apache.org/repos/asf/hbase/trunk hbase
Developer access
Everyone can access the Subversion repository via HTTP, but Committers must checkout the Subversion repository via HTTPS.
$ svn checkout https://svn.apache.org/repos/asf/hbase/trunk hbase
To commit changes to the repository, execute the following command to commit your changes (svn will prompt you for your password)
$ svn commit --username your-username -m "A message"
Access from behind a firewall
For those users who are stuck behind a corporate firewall which is blocking HTTP access to the Subversion repository, you can try to access it via the developer connection:
$ svn checkout https://svn.apache.org/repos/asf/hbase/trunk hbase
Access through a proxy
The Subversion client can go through a proxy, if you configure it to do so. First, edit your "servers" configuration file to indicate which proxy to use. The file's location depends on your operating system. On Linux or Unix it is located in the directory "~/.subversion". On Windows it is in "%APPDATA%\Subversion". (Try "echo %APPDATA%", note this is a hidden directory.)
There are comments in the file explaining what to do. If you don't have that file, get the latest Subversion client and run any command; this will cause the configuration directory and template files to be created.
Example: Edit the 'servers' file and add something like:
[global] http-proxy-host = your.proxy.name http-proxy-port = 3128
