It authenticates users via user certificates and enforce access -control based on configuration files. - -Starting up an HDFSPROXY server is similar to starting up an HDFS cluster. -Simply run "hdfsproxy" shell command. The main configuration file is -hdfsproxy-default.xml, which should be on the classpath. hdfsproxy-env.sh -can be used to set up environmental variables. In particular, JAVA_HOME should -be set. Additional configuration files include user-certs.xml, -user-permissions.xml and ssl-server.xml, which are used to specify allowed user -certs, allowed directories/files, and ssl keystore information for the proxy, -respectively. The location of these files can be specified in -hdfsproxy-default.xml. Environmental variable HDFSPROXY_CONF_DIR can be used to -point to the directory where these configuration files are located. The -configuration files of the proxied HDFS cluster should also be available on the -classpath (hdfs-default.xml and hdfs-site.xml). - -Mirroring those used in HDFS, a few shell scripts are provided to start and -stop a group of proxy servers. The hosts to run hdfsproxy on are specified in -hdfsproxy-hosts file, one host per line. All hdfsproxy servers are stateless -and run independently from each other. Simple load balancing can be set up by -mapping all hdfsproxy server IP addresses to a single hostname. Users should -use that hostname to access the proxy. If an IP address look up for that -hostname returns more than one IP addresses, an HFTP/HSFTP client will randomly -pick one to use. - -Command "hdfsproxy -reloadPermFiles" can be used to trigger reloading of -user-certs.xml and user-permissions.xml files on all proxy servers listed in -the hdfsproxy-hosts file. Similarly, "hdfsproxy -clearUgiCache" command can be -used to clear the UGI caches on all proxy servers. |
