[jira] [Updated] (HADOOP-14699) Impersonation errors with UGI after
second principal relogin
[ https://issues.apache.org/jira/browse/HADOOP-14699?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jeff Storck updated HADOOP-14699:
---------------------------------
Description:
Multiple principals that are logged in using UGI instances that are instantiated from a UGI class loaded by the same classloader will encounter problems when the second principal attempts to relogin and perform an action using a UGI.doAs(). An impersonation will occur and the operation attempted by the second principal after relogging in will fail. There should not be an implicit attempt to impersonate the second principal through the first principal that logged in.
I have created a GitHub project that exhibits the impersonation error with brief instructions on how to set up for the test and run it: https://github.com/jtstorck/ugi-test
