This was a version dependency issue. The class is not in 0.20.203.0. From: Artem Ervits [mailto:[email protected]] Sent: Wednesday, August 08, 2012 2:34 PM To: [email protected] Subject: Setting up HTTP authentication
Hello all, I followed the 1.0.3 docs to setup http simple authentication. I'd like to pass a username to open the web interface. My new settings for core-site.xml are below: <property> <name>hadoop.http.filter.initializers</name> <value>org.apache.hadoop.http.lib.StaticUserWebFilter,org.apache.hadoop.security.AuthenticationFilterInitializer</value> <description>HTTP Authentication document in hadoop tar file</description> </property> <property> <name>hadoop.http.authentication.type</name> <value>simple</value> <description>authentication type for web UI</description> </property> <property> <name>hadoop.http.authentication.token.validity</name> <value>36000</value> <description>how long authentication token is valid before it needs to be renewed</description> </property> <property> <name>hadoop.http.authentication.signature.secret</name> <value>test</value> <description>signature secret for signing authentication tokens</description> </property> <property> <name>hadoop.http.authentication.cookie.domain</name> <value></value> <description>domain to use for the http cookie that stores authentication token</description> </property> <property> <name>hadoop.http.authentication.simple.anonymous.allowed</name> <value>false</value> <description>anonymous web UI requests enabled or disabled</description> </property> Unfortunately, I don't have a 1.0.3 hadoop cluster handy and am testing this on 0.20.203.0. When I start the cluster, jobtracker doesn't start. Looking at the logs, I see the following: tasktracker log: 2012-08-08 13:40:26,178 WARN org.apache.hadoop.metrics2.impl.MetricsSystemImpl: Source name ugi already exists! and 2012-08-08 13:40:26,445 ERROR org.apache.hadoop.mapred.TaskTracker: Can not start task tracker because java.lang.RuntimeException: java.lang.ClassNotFoundException: org.apache.hadoop.security.AuthenticationFilterInitializer Namenode log shows: 2012-08-08 14:18:17,839 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: master/10.0.0.101:54310.

Already tried 0 time(s). My question is, is the org.apache.hadoop.security.AuthenticationFilterInitiazlier only available in 1.* releases or the problem is somewhere else? Thank you.
