Could not connect to Data Science Studio server

Hello,



I installed DSS on a mac, OS Yosemite 10.10.15.



While starting DSS, the chrome browser open an empty page with the following text :



"Could not connect to Data Science Studio server



Please check if DSS server is running.



Unknown error

HTTP code: 502, type: Gateway error"



I got no firewall on. DSS have been uninstalled 3 times.



 



Thanks in advance for your help.

It may take some time for DSS to load. Have you tried again after few minutes?

Well I waited a very long time, and tried again and again but it keeps giving me the same message.

OK. So there is a problem somewhere. We would need the logs in order to help you. Could you open a ticket on our support page (link in the right column)? Please attach the logs that you have in this folder: ~/Library/DataScienceStudio/dss_home/run/ (where ~ is the home folder of your user). Thanks.

there is an incompatibility issue with the startup scripts and recent JVMs (I am using 11), regarding logging of garbage collection events.

without knowing all of the details, I fixed the problem by hacking the script "java.py" in

/Applications/DataScienceStudio.app/Contents/Resources/kit/scripts/dkuinstall

and disable:

# if addGCLogging and jvm[0] in [ "hotspot", "openjdk" ]:

# if jvm[1] >= 9:

# ret += " -Xlog:gc,gc+cpu=info:stderr:t,um,l,ti,tg"

# elif gc == "g1":

# # G1 on Java 8 is very very verbose, so don't print GC details

# ret += " -Xloggc:/dev/stderr -XX:+PrintGCTimeStamps"

# else:

# ret += " -Xloggc:/dev/stderr -XX:+PrintGCDetails -XX:+PrintGCTimeStamps"

Hi,

Nice work ๐Ÿ™‚ We confirm that Java 11 is not yet supported. Support is upcoming in the next DSS release.

Hi,

just migrated to JDK 11 and seems it breaks my current install of dataiku (Dataiku 8 documentation says Java 11 is supported), with the same issue, but on Ubuntu

Is there an update to DSS? I am facing the same issue when I install DSS on Windows using linux sub system - Ubuntu and I am unable to locate java.py with the above content in order to disable them.
