我已成功在ec2群集上安装并启动了Zeppelin,其中包含spark 1.3和hadoop 2.4.1 on yarn。(如https://github.com/apache/incubator-zeppelin中所示)
但是,我看到zeppelin以'断开'状态开始(在右上角)。 根据日志,我发现zeppelin端口和websocket端口(zeppeling端口+ 1)都已启动且没有错误。此外,我看到这两个端口都没有被任何其他进程使用 zeppelin进程(pid)在两个端口上运行。 IP表是空白的。

zeppelin-env.sh:
export ZEPPELIN_PORT=8083
export HADOOP_CONF_DIR=/mnt/disk1/hadoop-2.4.1/etc/hadoop
export SPARK_HOME=/mnt/disk2/spark
在 zeppelin-site.xml 中,我只设置了服务器IP地址和端口,并为websocket端口设置了-1。
当我通过chorme访问websocket端口时,我得到“没有数据收到.. err_empty_reponse”和“无法加载网页,因为服务器没有发送任何数据”错误。
我在安装或配置过程中遗漏了什么?任何帮助表示赞赏。感谢。

我有一些使用apache zeppelin与IE或Chrome的经验。只需将您的IP地址添加到具有Internet选项的受信任站点即可。关闭IE或Chrome并重新启动它。然后打开IE或Chrome浏览器,你可以看到apache zeppelin的主页。

尝试在zeppelin.server.allowed.origins
中将属性*
设置为conf/zeppelin-site.xml
,并检查它是否是一个websocket问题。在列出了您想要允许的来源之后。
