Cannot open UI via default ip:ports

[staminna]

Hi

I am using Macos and latests docker. I am instaling and doing the instructions from top to bottum using first

$ docker-compose up.
$ docker network inspect docker-hadoop_default

        },
        "Options": {},
        "Labels": {}
    }
]

No errors are shown in the logs. I can't open up the User Interface of namenode. I didn't change anything and I am using http://172.19.0.2:50070/dfshealth.html#tab-overview which should be the default indicated by networks inspect.

Nothing seems wrong, yet it leads to

ERR_CONNECTION_TIMED_OUT

.

Is it mandatory to "Configure Environment Variables The configuration parameters can be specified in the hadoop.env file or as environmental variables for specific services (e.g. namenode, datanode etc.):" before trying to open the UI?

[gmouchakis]

It is not mandatory to make any changes to the provided configuration in order to access the UI. For me it works as it is so I cannot reproduce this. Do you get any other errors beside ERR_CONNECTION_TIMED_OUT?

[staminna]

No errors. But I did clone the Master branch. I deleted the master repository and cloned the latest branch. What is exactly the default url and port for this?

Having the same issue on my local

Environment: macOS High Sierra 10.13.6 Docker for Mac 2.0

[ueqt]

same issue

Environment: macOS Mojave 10.14.2 Docker for Mac 2.0.0.2

It's look like not assign localhost:port to link namenode:9870. So try to modify docker-compose.yml.

services:
  namenode:
    ...
    ports:
      - 9870:9870

And access url localhost:9870.

I have the same issue on my laptop, even after mapping ports 9870:9870 of namenode container

Environment: macOS Mojave 10.14.4 Docker for Mac 2.0.0.3

1. Update the ports as mentioned above
2. Run docker-machine config {your_machine_name}. Notice the machine IP in the last line

~user ~> docker-machine config default
--tlsverify
--tlscacert="/Users/~user/.docker/machine/machines/default/ca.pem"
--tlscert="/Users/~user/.docker/machine/machines/default/cert.pem"
--tlskey="/Users/~user/.docker/machine/machines/default/key.pem"
-H=tcp://192.168.64.3:2376

3. Access namenode via http://{Docker Machine IP}:9870/dfshealth.html#tab-overview
