Jason Lowe commented on MAPREDUCE-3976: --------------------------------------- Test failures appear to be another occurrence of MAPREDUCE-3729 rather than a result of this patch. I was unable to reproduce the problem locally. All of the test failures are of the form: {noformat} chmod: cannot access `/tmp/hadoop-jenkins/mapred/staging/jenkins-1903973876/.staging/job_local_0001': No such file or directory {noformat} > TestRMContainerAllocator failing > -------------------------------- > > Key: MAPREDUCE-3976 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3976 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 0.23.2 > Reporter: Bikas Saha > Assignee: Jason Lowe > Attachments: MAPREDUCE-3976.patch > > > The following stack trace is being generated > ======== > org.apache.hadoop.metrics2.MetricsException: Metrics source JvmMetrics > already exists! > at > org.apache.hadoop.metrics2.lib.DefaultMetricsSystem.newSourceName(DefaultMetricsSystem.java:126) > at > org.apache.hadoop.metrics2.lib.DefaultMetricsSystem.sourceName(DefaultMetricsSystem.java:107) > at > org.apache.hadoop.metrics2.impl.MetricsSystemImpl.register(MetricsSystemImpl.java:216) > at > org.apache.hadoop.metrics2.source.JvmMetrics.create(JvmMetrics.java:80) > at > org.apache.hadoop.mapreduce.v2.app.metrics.MRAppMetrics.create(MRAppMetrics.java:58) > at > org.apache.hadoop.mapreduce.v2.app.metrics.MRAppMetrics.create(MRAppMetrics.java:54) > at > org.apache.hadoop.mapreduce.v2.app.MRAppMaster.<init>(MRAppMaster.java:186) > at > org.apache.hadoop.mapreduce.v2.app.MRAppMaster.<init>(MRAppMaster.java:170) > at org.apache.hadoop.mapreduce.v2.app.MRApp.<init>(MRApp.java:160) > at > org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator$1.<init>(TestRMContainerAllocator.java:372) > at > org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator.testReportedAppProgress(TestRMContainerAllocator.java:371) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > at java.lang.reflect.Method.invoke(Method.java:597) > at > org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) > ======== > This test fails when git trunk is reset to - commit > 6689d99b38c7c562e8cae484207ad30ad7b56eb5 > but passes when git trunk is reset to - commit > f429fdaf78a02211c4faee54b1ee92822edc5741 -- This message is automatically generated by JIRA.
