连接到Docker中运行的HBase

我无法连接到Windows上的Docker中运行的HBase(banno/hbase-standalone映像).但是,我可以连接到本地安装的HBase.

banno/hbase-standalone图像使用以下命令运行:

docker run -d -p 2181:2181 -p 60000:60000 -p 60010:60010 -p 60020:60020 -p 60030:60030 banno/hbase-standalone

我还设置了端口转发boot2docker-vm(在Windows上运行时需要):

我可以成功telnet到我的localhost上的所有端口.

接下来,这是我们在测试中使用的代码示例:

Configuration config = HBaseConfiguration.create();
config.clear();
config.setInt("timeout", 12000);
config.set("zookeeper.znode.parent", "/hbase");
config.set("hbase.zookeeper.quorum", "127.0.0.1");
config.set("hbase.zookeeper.property.clientPort", "2181");
config.set("hbase.master", "127.0.0.1:60000");

final Configuration configuration = HBaseConfiguration.create(config);

JobDefinition.Buildable.dumpProperties(configuration, newArrayList("hbase.*"));

HBaseAdmin.checkHBaseAvailable(config);

这导致以下异常

这是可以解释的.我们运行Windows,这需要boot2docker-vm使用NAT运行虚拟机.图像的Docker容器boot2docker-vm也在使用NAT 内部运行.但是,端口对运行测试的主机"可见",因为Docker容器导出端口,boot2docker-vm并将端口转发给主机.该名称a3e6c240af20实际上来自Docker容器ID,因此可能a3e6c240af20是Docker容器的主机名:

CONTAINER ID        IMAGE                           COMMAND                CREATED             STATUS              PORTS                                                                                                                            NAMES
a3e6c240af20        banno/hbase-standalone:latest   "/bin/sh -c '/opt/hb   24 minutes ago      Up 24 minutes       0.0.0.0:2181->2181/tcp, 0.0.0.0:60000->60000/tcp, 0.0.0.0:60010->60010/tcp, 0.0.0.0:60020->60020/tcp, 0.0.0.0:60030->60030/tcp   agitated_wozniak

我不确定HBase通信是如何工作的,但显然它会对实例进行RPC调用.HBase Docker返回其主机名,希望客户端在那里调用它.但由于两者boot2docker-vm和Docker容器都使用NAT运行,因此主机没有看到Docker容器.

我试图添加a3e6c240af20到我的主机文件:

127.0.0.1 a3e6c240af20

然后我在RPC调用期间得到了一个不同的错误,这实际上对我没什么帮助:

有人建议如何解决这个问题吗？
