Chuan Liu created HADOOP-8455: --------------------------------- Summary: Address user name format on domain joined Windows machines Key: HADOOP-8455 URL: https://issues.apache.org/jira/browse/HADOOP-8455 Project: Hadoop Common Issue Type: Bug Affects Versions: 1.1.0, 0.24.0 Reporter: Chuan Liu Assignee: Ivan Mitic Priority: Minor
For a domain joined Windows machine, user name along is not a unique identifier. User name plus domain name is need in order to unique identify the user. For example, we can have both ‘Win1\Alex’ and ‘Redmond\Alex’ on a computer named Win1 that joins Redmond domain. In order to avoid ambiguity, ‘whoami’ on Windows and the new ‘winutils’ created in [Hadoop-8235|https://issues.apache.org/jira/browse/HADOOP-8235] both return [domain]\[username] as the username. In Hadoop, we only use user name right now. This may lead to some inconsistency, and production bugs if users of the same name exist on the machine. -- This message is automatically generated by JIRA.
