Zhankun Tang commented on YARN-10041: ------------------------------------- [~bzhaoopenstack], thanks for catching this. Would you like to provide a patch for this? > Should not use AbstractPath to create unix domain socket > -------------------------------------------------------- > > Key: YARN-10041 > URL: https://issues.apache.org/jira/browse/YARN-10041 > Project: Hadoop YARN > Issue Type: Bug > Components: client > Environment: X86/ARM > OS: ubuntu 1804 > java: java8 > Reporter: zhao bo > Priority: Major > > This issue hits by a very coincidental scene. That 's happend when we test on > ARM. > The test case is: > org.apache.hadoop.yarn.csi.client.TestCsiClient.testIdentityService > > The step is: > If we make the hadoop source code dir to a very deep dir path, this case > would be pass at the first time running, but always fail in the following > tries. > The official jenkins doesn't cover this, because it runs on Docker container > and just run test 1 time. So it looks like alway pass. > > The key point is the UNIX domain socket path exceed the limit of > UNIX_PATH_MAX(108). Please see [1] > > This issue is very difficult to locate, as it will always return binding > failed when we exec the test. > > Also I saw the hadoop code in trunk branch, the code use the AbsolutePath to > create the UNIX DOMAIN SOCKET file. The source code is [2]. So that can not > forbid to hit this issue. That's good to provide a second way to set the > socket path to '/tmp' or any place when exec this test. > [1] > [https://serverfault.com/questions/641347/check-if-a-path-exceeds-maximum-for-unix-domain-socket] > [2] > [https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-csi/src/test/java/org/apache/hadoop/yarn/csi/client/TestCsiClient.java#L48] -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
