Hi, Our application runs in Tomcat 5.5, Java 6.17, with JAAS. We give our own implementation to LoginModule and we start Tomcat with -Djava.security.auth.login.config. We use Hadoop 0.20.203.0.
We want to execute Hadoop jobs, or Hadoop FileSystem methods from within our application, remotely. Problem: once we use/initialize Hadoop's configuration (either by calling org.apache.hadoop.fs.FileSystem.get(Configuration) or by calling org.apache.hadoop.mapred.JobClient.runJob(JobConf)), the implementation of LoginModule changes from ours to org.apache.hadoop.security.UserGroupInformation.HadoopLoginModule, and we cannot login to our application anymore! However, there is no problem with the remote execution of the jobs. I saw this thread (Use JAAS LoginContext for our login<https://issues.apache.org/jira/browse/HADOOP-6299>). Does it fixes the problem? It looks like it will still create a new LoginModule? Won't it?
