1：安装好hive，准备启动的时候出现下面的错误（由于hive是基于Hadoop的，所以必须先将你的集群启动起来，我就是没有启动集群，直接启动hive导致的错误）：
1 [root@master bin]# ./hive 2 3 Logging initialized using configuration in jar:file:/home/hadoop/soft/apache-hive-1.2.1-bin/lib/hive-common-1.2.1.jar!/hive-log4j.properties 4 Exception in thread "main" java.lang.RuntimeException: java.net.ConnectException: Call From master/192.168.199.130 to master:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused 5 at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:522) 6 at org.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:677) 7 at org.apache.hadoop.hive.cli.CliDriver.main(CliDriver.java:621) 8 at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 9 at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) 10 at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 11 at java.lang.reflect.Method.invoke(Method.java:606) 12 at org.apache.hadoop.util.RunJar.run(RunJar.java:221) 13 at org.apache.hadoop.util.RunJar.main(RunJar.java:136) 14 Caused by: java.net.ConnectException: Call From master/192.168.199.130 to master:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused 15 at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) 16 at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) 17 at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) 18 at java.lang.reflect.Constructor.newInstance(Constructor.java:526) 19 at org.apache.hadoop.net.NetUtils.wrapWithMessage(NetUtils.java:791) 20 at org.apache.hadoop.net.NetUtils.wrapException(NetUtils.java:731) 21 at org.apache.hadoop.ipc.Client.call(Client.java:1473) 22 at org.apache.hadoop.ipc.Client.call(Client.java:1400) 23 at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:232) 24 at com.sun.proxy.$Proxy17.getFileInfo(Unknown Source) 25 at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.getFileInfo(ClientNamenodeProtocolTranslatorPB.java:752) 26 at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 27 at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) 28 at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 29 at java.lang.reflect.Method.invoke(Method.java:606) 30 at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:187) 31 at org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:102) 32 at com.sun.proxy.$Proxy18.getFileInfo(Unknown Source) 33 at org.apache.hadoop.hdfs.DFSClient.getFileInfo(DFSClient.java:1977) 34 at org.apache.hadoop.hdfs.DistributedFileSystem$18.doCall(DistributedFileSystem.java:1118) 35 at org.apache.hadoop.hdfs.DistributedFileSystem$18.doCall(DistributedFileSystem.java:1114) 36 at org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81) 37 at org.apache.hadoop.hdfs.DistributedFileSystem.getFileStatus(DistributedFileSystem.java:1114) 38 at org.apache.hadoop.fs.FileSystem.exists(FileSystem.java:1400) 39 at org.apache.hadoop.hive.ql.session.SessionState.createRootHDFSDir(SessionState.java:596) 40 at org.apache.hadoop.hive.ql.session.SessionState.createSessionDirs(SessionState.java:554) 41 at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:508) 42 ... 8 more 43 Caused by: java.net.ConnectException: Connection refused 44 at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) 45 at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:739) 46 at org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:206) 47 at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:530) 48 at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:494) 49 at org.apache.hadoop.ipc.Client$Connection.setupConnection(Client.java:608) 50 at org.apache.hadoop.ipc.Client$Connection.setupIOstreams(Client.java:706) 51 at org.apache.hadoop.ipc.Client$Connection.access$2800(Client.java:369) 52 at org.apache.hadoop.ipc.Client.getConnection(Client.java:1522) 53 at org.apache.hadoop.ipc.Client.call(Client.java:1439) 54 ... 28 more 55 [root@master bin]#
2：启动你的集群，然后再启动你的hive再次尝试：
1 [root@master bin]# start-dfs.sh 2 Starting namenodes on [master] 3 master: starting namenode, logging to /home/hadoop/soft/hadoop-2.6.4/logs/hadoop-root-namenode-master.out 4 master: starting datanode, logging to /home/hadoop/soft/hadoop-2.6.4/logs/hadoop-root-datanode-master.out 5 slaver2: starting datanode, logging to /home/hadoop/soft/hadoop-2.6.4/logs/hadoop-root-datanode-slaver2.out 6 slaver1: starting datanode, logging to /home/hadoop/soft/hadoop-2.6.4/logs/hadoop-root-datanode-slaver1.out 7 Starting secondary namenodes [master] 8 master: starting secondarynamenode, logging to /home/hadoop/soft/hadoop-2.6.4/logs/hadoop-root-secondarynamenode-master.out 9 [root@master bin]# start-yarn.sh 10 starting yarn daemons 11 starting resourcemanager, logging to /home/hadoop/soft/hadoop-2.6.4/logs/yarn-hadoop-resourcemanager-master.out 12 slaver1: starting nodemanager, logging to /home/hadoop/soft/hadoop-2.6.4/logs/yarn-root-nodemanager-slaver1.out 13 slaver2: starting nodemanager, logging to /home/hadoop/soft/hadoop-2.6.4/logs/yarn-root-nodemanager-slaver2.out 14 master: starting nodemanager, logging to /home/hadoop/soft/hadoop-2.6.4/logs/yarn-root-nodemanager-master.out 15 [root@master bin]# jps 16 23933 ResourceManager 17 24081 NodeManager 18 23391 SecondaryNameNode 19 22992 NameNode 20 24147 Jps
3：启动完集群以后再次启动hive的时候依旧还报错，不过是新的错误，如下所示，解决方法见下篇：

停更......
