Unit test failure in TestUserGroupInformation.testGetServerSideGroups ---------------------------------------------------------------------
Key: HADOOP-7290 URL: https://issues.apache.org/jira/browse/HADOOP-7290 Project: Hadoop Common Issue Type: Bug Components: test Affects Versions: 0.23.0 Environment: Linux 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode) Reporter: Trevor Robinson Priority: Minor Testsuite: org.apache.hadoop.security.TestUserGroupInformation Tests run: 14, Failures: 1, Errors: 0, Time elapsed: 0.278 sec ------------- Standard Output --------------- trobinson:users guest git ------------- ---------------- --------------- Testcase: testGetServerSideGroups took 0.051 sec FAILED expected:<g[ues]t> but was:<g[i]t> junit.framework.AssertionFailedError: expected:<g[ues]t> but was:<g[i]t> at org.apache.hadoop.security.TestUserGroupInformation.testGetServerSideGroups(TestUserGroupInformation.java:94) It seems like the test is assuming that the groups returned by UserGroupInformation.getGroupNames() are in the same order as those returned by executing `id -Gn`. getGroupNames() only documents that the primary group is first, and `man id` doesn't document any ordering, so it seems like the test needs to be reworked to remove that assumption. -- This message is automatically generated by JIRA.
