Subject [jira] [Commented] (HADOOP-11683) Need a plugin API to translate long principal names to local OS user names arbitrarily
Date Sat, 15 Aug 2015 00:26:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14697990#comment-14697990
] 

roger mak commented on HADOOP-11683:
------------------------------------

The +1 failed test case, org.apache.hadoop.net.TestClusterTopology.testChooseRandom, has no
relation with the change. It also passed in my local environment.

The other 6 failed test cases are there before and also have no relation with the change:
org.apache.hadoop.ha.TestZKFailoverController.testGracefulFailoverFailBecomingStandbyAndFailFence
org.apache.hadoop.ha.TestZKFailoverController.testGracefulFailover
org.apache.hadoop.ha.TestZKFailoverController.testGracefulFailoverFailBecomingStandby
org.apache.hadoop.ha.TestZKFailoverController.testGracefulFailoverMultipleZKfcs
org.apache.hadoop.ha.TestZKFailoverController.testGracefulFailoverFailBecomingActive
org.apache.hadoop.net.TestNetUtils.testNormalizeHostName

Please reconsider the test result (or rerun the test). Thanks.

> We need a plugin API to translate long principal names (e.g. john.doe@EXAMPLE.COM) to
local OS user names (e.g. user123456) arbitrarily.
> For some organizations the name translation is straightforward (e.g. john.doe@EXAMPLE.COM
to john_doe), and the hadoop.security.auth_to_local configurable mapping is sufficient to
resolve this (see HADOOP-6526). However, in some other cases the name translation is arbitrary
and cannot be generalized by a set of translation rules easily.
