Question

我试图在本地计算机（OSX）中运行Pig和Hadoop来测试脚本，但我似乎无法在Docker中连接Hadoop。

我在本地设置Pig。我从https://hub.docker.com/r/sequenceiq/hadoop-docker/安装了Hadoop，并使用此命令运行计算机

docker run -it sequenceiq/hadoop-docker:2.7.0 -p 50010:50010 -p 19888:19888 /etc/bootstrap.sh -bash

我可以启动Hadoop docker。

我查看Dockerfile以查看哪些端口已曝光。 https://github.com/sequenceiq/hadoop-docker/blob/master/Dockerfile#L103

这是我的hadoop-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
  <name>hadoop.tmp.dir</name>
  <value>/tmp/hadoop-${user.name}</value>
</property>
<property>
  <name>fs.default.name</name>
  <value>hdfs://192.168.99.100:50010</value>
</property>
<property>
  <name>mapred.job.tracker</name>
  <value>hdfs://192.168.99.100:19888</value>
</property>
<property> 
  <name>dfs.replication</name>
  <value>8</value>
</property>
<property>
  <name>mapred.child.java.opts</name>
  <value>-Xmx512m</value>
</property>
</configuration>

当我运行Pig时，我收到此错误。

我错过了什么吗？

Answer 1

Docker在OSX（和Windows）上的虚拟机中运行。

公开docker端口与VirtualBox中的转发端口不同。

您是否已在设置＆gt;下的VirtualBox中转发相应的端口？网络＆gt;高级＆gt;转发端口？

Pig`无法在Docker ENV中为Hadoop集群创建DataStorage`
