hadoop - Pig `Failed to create DataStorage`到Docker ENV中的Hadoop集群

Question

我正在尝试在本地计算机(OSX)中运行Pig和Hadoop来测试脚本，但似乎无法在Docker中连接Hadoop。

我在本地设置了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 。

我查看了 Dockerfile以查看暴露了哪些端口。 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，出现此错误。

我有什么想念的吗？

Docker在OSX(和Windows)上的虚拟机中运行。

暴露docker端口与VirtualBox中的转发端口不同。

您是否已在VirtualBox中的“设置”>“网络”>“高级”>“端口转发”下转发了适当的端口？
