| HDFS Proxy is a proxy server through which a hadoop client (through HSFTP) or a standard |
| HTTPS client (wget, curl, etc) can talk to a hadoop server and more importantly pull data |
| from the sever. It put an access control layer in front of hadoop namenode server and extends |
| its functionalities to allow hadoop cross-version data transfer. |
| |
| HDFSPROXY can be configured/started via either Jetty or Tomcat with different supporting features. |
| |
| A) With Jetty-based Installation, supporting features include: |
| > Single Hadoop source cluster data transfer |
| > Single Hadoop version data transfer |
| > Authenticate users via user SSL certificates with ProxyFilter installed |
| > Enforce access control based on configuration files. |
| |
| B) With Tomcat-based Installation, supporting features include: |
| > Multiple Hadoop source cluster data transfer |
| > Multiple Hadoop version data transfer |
| > Authenticate users via user SSL certificates with ProxyFilter installed |
| > Authentication and authorization via LDAP with LdapIpDirFilter installed |
| > Access control based on configuration files if ProxyFilter is installed. |
| > Access control based on LDAP entries if LdapIpDirFilter is installed. |
| > Standard HTTPS Get Support for file transfer |
| |
| The detailed configuration/set-up guide is in the Forrest |
| documentation, which can be found at $HADOOP_PREFIX/docs. In order to build the |
| documentation on your own from source please use the following command in |
| the downloaded source folder: |
| |
| ant docs -Dforrest.home=path to forrest -Djava5.home= path to jdk5. |
| |
| The documentation so built would be under $HADOOP_PREFIX/build/docs |
