Re: ContainerCreating: Creating engine container


there was a problem with wildcard dns.


i built my own dns server and i went though and image and containers are created.


i can created and launch the projects.

Re: ContainerCreating: Creating engine container


the images/containers cannot resolve hostname with names but IP. scala project comes with error.

Setting default log level to "ERROR".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
17/07/10 08:26:54 ERROR spark.SparkContext: Error initializing SparkContext.

if i use terminal, i cannot ping the server with their names but i can with IPs

How to check the engine status in the backend ?


I have installed Cloudera Data Science Workbench after fulfilling prerequisites.

cdsw status and cdsw validate doesn't show any errors or warnings. But, when i open the workbench and try to start a scala,python or R sessions, it's showing the "ContainerCreating: Creating engine container" forever with red cursor at the bottom input box.

when i go back to projects and reopen the session, it's showing green.

But it doesn't take any input after that.

I somehow tried to check with "docker ps" command which shows only docker containers which are created when i submit the job which is not much informative.


I'm curious to check the logs about what's happening in the backend.


Can someone help the approach to troubleshoot this issue ?


Does anyone know how exactly it works in the backend ?

+1 got the same problem here with version 1.2.2.

I didn't observe the same with version 1.1.

What is your version venkatachetkuri?
