Hi Terry, I see your email several days ago, but I have no idea about the issue. It should be some environment problems I believe.
Are you setting up the Hadoop cluster by manual? Usually, if you're not a Hadoop expert, we recommend to start with the commercial Hadoop releases like HDP, CDH, AWS EMR, etc; That could save your lots of time and effort. 2018-08-10 10:07 GMT+08:00 Terry Lu <[email protected]>: > Hi： > > 我们在使用 Kylin(kylin版本是2.3, Hadoop是apache hadoop-2.7.3，而且集群全部启动正常 )在创建 > Cube到#3 Step Name: Extract Fact Table Distinct Columns时报 localhost:18032 > failed错误，然后就将yarn.resourcemanager.address信息添加到了kylin_job_conf.xml这个文件中，原来 > Cube创建只能执行到第三步就报错，此时可以执行到第十步， 但此问题还是依然存在，而这个问题也没有解决， > 附件是Kylin的日志信息，还有kylin及yarn、mapred的配置文件，请求大师能协助处理一下，我们万分感激！ > > 以下是#10 Step Name: Build Cube In-Mem Duration: 20.19 mins Waiting: 0 > seconds的错误信息如下： > > > > java.net.ConnectException: Call From hsmaster/10.9.0.86 to localhost:18032 > failed on connection exception: java.net.ConnectException: Connection > refused; For more details see: > http://wiki.apache.org/hadoop/ConnectionRefused > at sun.reflect.GeneratedConstructorAccessor75.newInstance(Unknown > Source) > at > sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) > at java.lang.reflect.Constructor.newInstance(Constructor.java:423) > at org.apache.hadoop.net.NetUtils.wrapWithMessage(NetUtils.java:792) > at org.apache.hadoop.net.NetUtils.wrapException(NetUtils.java:732) > at org.apache.hadoop.ipc.Client.call(Client.java:1479) > at org.apache.hadoop.ipc.Client.call(Client.java:1412) > at > org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:229) > at com.sun.proxy.$Proxy66.getNewApplication(Unknown Source) > at > org.apache.hadoop.yarn.api.impl.pb.client.ApplicationClientProtocolPBClientImpl.getNewApplication(ApplicationClientProtocolPBClientImpl.java:221) > at sun.reflect.GeneratedMethodAccessor122.invoke(Unknown Source) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at > org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:191) > at > org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:102) > at com.sun.proxy.$Proxy67.getNewApplication(Unknown Source) > at > org.apache.hadoop.yarn.client.api.impl.YarnClientImpl.getNewApplication(YarnClientImpl.java:219) > at > org.apache.hadoop.yarn.client.api.impl.YarnClientImpl.createApplication(YarnClientImpl.java:227) > at > org.apache.hadoop.mapred.ResourceMgrDelegate.getNewJobID(ResourceMgrDelegate.java:187) > at org.apache.hadoop.mapred.YARNRunner.getNewJobID(YARNRunner.java:231) > at > org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:153) > at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1290) > at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1287) > at java.security.AccessController.doPrivileged(Native Method) > at javax.security.auth.Subject.doAs(Subject.java:422) > at > org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1698) > at org.apache.hadoop.mapreduce.Job.submit(Job.java:1287) > at > org.apache.kylin.engine.mr.common.AbstractHadoopJob.waitForCompletion(AbstractHadoopJob.java:175) > at > org.apache.kylin.engine.mr.steps.InMemCuboidJob.run(InMemCuboidJob.java:121) > at > org.apache.kylin.engine.mr.common.MapReduceExecutable.doWork(MapReduceExecutable.java:130) > at > org.apache.kylin.job.execution.AbstractExecutable.execute(AbstractExecutable.java:162) > at > org.apache.kylin.job.execution.DefaultChainedExecutable.doWork(DefaultChainedExecutable.java:67) > at > org.apache.kylin.job.execution.AbstractExecutable.execute(AbstractExecutable.java:162) > at > org.apache.kylin.job.impl.threadpool.DefaultScheduler$JobRunner.run(DefaultScheduler.java:300) > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > at java.lang.Thread.run(Thread.java:748) > Caused by: java.net.ConnectException: Connection refused > at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) > at > sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:717) > at > org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:206) > at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:531) > at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:495) > at > org.apache.hadoop.ipc.Client$Connection.setupConnection(Client.java:614) > at > org.apache.hadoop.ipc.Client$Connection.setupIOstreams(Client.java:712) > at org.apache.hadoop.ipc.Client$Connection.access$2900(Client.java:375) > at org.apache.hadoop.ipc.Client.getConnection(Client.java:1528) > at org.apache.hadoop.ipc.Client.call(Client.java:1451) > ... 31 more > result code:2 > > > -- Best regards, Shaofeng Shi 史少锋
