hadoop报错：Does not contain a valid host:port authority

今天用sbin/start-yarn.sh启动yarn的时候，遇到下面的错误

　　经过排查，发现是mapred-site.xml中配置错误，如下：

<property>
  <name>mapreduce.jobhistory.address</name>
  <value>master</value>
  <description>job history server</description>
</property>

<property>
  <name>mapreduce.jobhistory.webapp.address</name>
  <value>master</value>
  <description>job history server</description>
</property>

　　address应该包含端口号，而配置文件中只指定了主机名，所以加上端口号就好了

<property>
  <name>mapreduce.jobhistory.address</name>
  <value>master:7001</value>
  <description>job history server</description>
</property>

<property>
  <name>mapreduce.jobhistory.webapp.address</name>
  <value>master:8001</value>
  <description>job history server</description>
</property>

　　遇到以上错误的朋友，不妨看一下core-site.xml,hdfs-site.xml,mapred-site.xml,yarn-site.xml这几个配置文件中的地址格式是否正确，另外value两端最好不要出现空格,比如下面的格式可能会报错(master前边有空格)

<property>
  <name>mapreduce.jobhistory.address</name>
  <value> master</value>
  <description>job history server</description>
</property>

hadoop报错：Does not contain a valid host:port authority的相关文章

Does not contain a valid host:port authority: Master:8031 (configuration property &#39;yarn.resourcemanager.resource-tracker.address&#39;)

问题解决: 这个错误是:yarn里面的配置的格式有错误:如: <property> <name>yarn.resourcemanager.address</name> <value>Master:8032</value> </property> <property> 在<value>标签之间不能有空格.去掉空格OK. 异常堆栈如下 2014-08-30 10:20:30,171 INFO org.apache.

最近使用CentOS7学习,安装安装Apache时候,使用yum安装Apache报错:本文适合CentOS7和RHEL7 # yum install httpd 出现:cannot find a valid baseurl for repo:base/7/x86_64. 针对这个问题,网上有大量的解决方案,说是网络不通的,比如: 修改: vi /etc/sysconfig/network-scripts/ifcfg-eth0(每个机子都可能不一样,但格式会是"ifcfg-eth数字")
