Hadoop多节点群集:异常:java.net.ConnectException:连接被拒绝
我使用Hadoop多节点群集:异常:java.net.ConnectException:连接被拒绝,hadoop,Hadoop,我使用http://pingax.com/install-apache-hadoop-ubuntu-cluster-setup/: 名称节点:node04 数据节点:node01 数据节点:node02 数据节点:node03 我只能看到集群中运行的两个节点(node01、node03)。Node02有一个日志,错误消息如下: 2015-12-11 10:15:18,698 INFO org.apache.hadoop.ipc.Client: Retrying connect to server
http://pingax.com/install-apache-hadoop-ubuntu-cluster-setup/
:
名称节点:node04
数据节点:node01
数据节点:node02
数据节点:node03
我只能看到集群中运行的两个节点(node01、node03)。Node02有一个日志,错误消息如下:
2015-12-11 10:15:18,698 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: node04/127.17.0.224:9000. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)
2015-12-11 10:15:19,699 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: node04/127.17.0.224:9000. Already tried 1 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)
2015-12-11 10:15:20,699 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: node04/127.17.0.224:9000. Already tried 2 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)
每个节点/etc/hosts都包含以下内容:
127.0.0.1 localhost
127.17.0.221 node01
127.17.0.222 node02
127.17.0.223 node03
127.17.0.224 node04
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
和/etc/hadoop/masters包含node04
,/etc/hadoop/slaves包含node01 node02
和node03
你能帮我弄清楚怎么去吗?
谢谢 执行以下操作:
telnet node04 9000
和ping node04
命令
确认节点02和节点04之间存在连接另请参阅telnet node04 9000的以下输出:Trying 127.17.0.224。。。telnet:无法连接到远程主机:连接被拒绝PING node04已输出:PING node04(127.17.0.224)56(84)字节的数据。来自node04的64字节(127.17.0.224):icmp_-seq=1 ttl=64 time=0.020 ms来自node04的64字节(127.17.0.224):icmp_-seq=2 ttl=64 time=0.008 msi对于core-site.xml和hfs-site.xmlI具有相同的配置。我可以在node04(线虫)和node02(数据节点)之间进行ssh。您检查了提到的链接吗。
