Subject [jira] [Commented] (YARN-1681) When "banned.users" is not set in LCE's container-executor.cfg, submit job with user in DEFAULT_BANNED_USERS will receive unclear error message
Date Sun, 02 Feb 2014 16:54:08 GMT

    [ https://issues.apache.org/jira/browse/YARN-1681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13888967#comment-13888967
] 

Zhichun Wu commented on YARN-1681:
----------------------------------

When "banned.users" is not set, banned_users will be NULL in container-executor.c, and  "free_values(banned_users);"
will be "free_values(NULL);" and error occurs:
{code}
 for(; *banned_user; ++banned_user) {
    if (strcmp(*banned_user, user) == 0) {
      free(user_info);
      if (banned_users != (char**)DEFAULT_BANNED_USERS) {
        free_values(banned_users);
      }
      fprintf(LOGFILE, "Requested user %s is banned\n", user);
      return NULL;
    }
  }
{code}

in DEFAULT_BANNED_USERS will receive unclear error message

> When using LCE in a secure setup, if "banned.users" is not set in container-executor.cfg,
submit job with user in DEFAULT_BANNED_USERS ("mapred", "hdfs", "bin", 0)  will receive unclear
error message.
> for example, if we use hdfs to submit a mr job, we may see the following the yarn app
overview page:
> {code}
> appattempt_1391353981633_0003_000002 exited with exitCode: -1000 due to: Application
application_1391353981633_0003 initialization failed (exitCode=139) with output: 
> {code}
> while the prefer error message may look like:
> {code}
> appattempt_1391353981633_0003_000002 exited with exitCode: -1000 due to: Application
application_1391353981633_0003 initialization failed (exitCode=139) with output: Requested
user hdfs is banned 
> {code}
> just a minor bug and I would like to start contributing to hadoop-common with it:)
