Branch-2 builds have been disabled for a while: https://builds.apache.org/view/H-L/view/Hadoop/job/hadoop-qbt-branch2-java7-linux-x86/ A test run here causes hdfs tests to hang: https://builds.apache.org/view/H-L/view/Hadoop/job/hadoop-qbt-branch2-java7-linux-x86-jhung/4/ Running hadoop-hdfs tests locally reveal some errors such as:{noformat}[ERROR] testComplexAppend2(org.apache.hadoop.hdfs.TestFileAppend2) Time elapsed: 0.059 s <<< ERROR! java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:714) at org.apache.hadoop.hdfs.server.namenode.FSImage.saveFSImageInAllDirs(FSImage.java:1164) at org.apache.hadoop.hdfs.server.namenode.FSImage.saveFSImageInAllDirs(FSImage.java:1128) at org.apache.hadoop.hdfs.server.namenode.FSImage.format(FSImage.java:174) at org.apache.hadoop.hdfs.server.namenode.NameNode.format(NameNode.java:1172) at org.apache.hadoop.hdfs.server.namenode.NameNode.format(NameNode.java:403) at org.apache.hadoop.hdfs.DFSTestUtil.formatNameNode(DFSTestUtil.java:234) at org.apache.hadoop.hdfs.MiniDFSCluster.createNameNodesAndSetConf(MiniDFSCluster.java:1080) at org.apache.hadoop.hdfs.MiniDFSCluster.initMiniDFSCluster(MiniDFSCluster.java:883) at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:514) at org.apache.hadoop.hdfs.MiniDFSCluster$Builder.build(MiniDFSCluster.java:473) at org.apache.hadoop.hdfs.TestFileAppend2.testComplexAppend(TestFileAppend2.java:489) at org.apache.hadoop.hdfs.TestFileAppend2.testComplexAppend2(TestFileAppend2.java:543) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43){noformat} I was able to get more tests passing locally by increasing the max user process count on my machine. But the error suggests that there's an issue in the tests themselves. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
