So this matters. Tony: can you replicate these problems on hadoop-trunk? As that's where all fixes to things like test stability are going to go, with backporting as and when appropriate. I doubt anybody is going to worry about an unstable test on 2.4.x, on the basis that the problems may already have been fixed. You can also have a search for JIRAs with the names in the test to see if they have been reported and fixed already. > Several tests are not stable (on OpenJDK / x86_64 / RHEL 7.1) > ------------------------------------------------------------- > > Key: HADOOP-11617 > URL: https://issues.apache.org/jira/browse/HADOOP-11617 > Project: Hadoop Common > Issue Type: Bug > Environment: RHEL 7.1 / x86_64 > Reporter: Tony Reix > > I'm now porting Hadoop 2.4.1 on PPC64 HW. > In order to have an idea about the stability of the tests, I've run several times all Hadoop tests in a RHEL 7.1 / x86_64 / OpenJDK environment. > I've run it 12 times, for now, on the EXACT same environment. > Using some tool, I have extracted the list of tests that do not always produce the same results, listed below, showing some test unstability. > I 'm now doing the same for version 2.6.0 on OpenJDK/Ubuntu/x86_64. > Report gives: > test-name N: T F E S | > where: > - N is the number of the test log file > - and: > T: Tests run > F: Failure > E: Error > S: Skipped > As an example (see below for full data): > hdfs.server.datanode.TestDeleteBlockPool 0: 2 0 0 0 | > ........ > hdfs.server.datanode.TestDeleteBlockPool 4: 2 0 1 0 | > ........ > hdfs.server.datanode.TestDeleteBlockPool 11: 2 0 0 0 | > means that this test, out of 12 runs, had an error once, with 0 Failure and 0 Skipped test. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
