Create Dataset fails

[skef]

Hello,

the following error is occurring, when I try to create a new Dataset with analytics v. 8.3.040507:

Execution error in service script [CreateDatasetAMS] :: Error returned from service [500]: Unexpected error occurred:Unable to parse queuedStartDateTime: 2018-10-23T11:50:15.174Z]

How can I fix this error?

Hello,

I will be assisting you with this.

Can you please check if the zookeeper is in the running state or paused state?

Thanks

Best regards,

Hello,

thanks for your fast reply. How can I check this?

[pshubham]

Hello,

Can you please provide below information:

1. Are you using a VM or native installation?
2. What operating system are you using?

Thanks 

Best Regards,

I am using a native installation, on a Linux machine

I think zookeeper is running, since the analytics things (DataThing, ResultThing etc) are running and 

ps aux | grep zookeeper

tells me, that there is a java process running which is related to zookeeper

[pshubham]

Hello,

You can try running the below command and see if zookeeper process is running or not:

sudo /opt/ThingworxAnalyticsServer/bin/twas.sh list

OR

sudo /opt/ThingworxAnalyticsServer/bin/twas.sh status 

Kindly adjust the path according to your installation path.

Thanks

Best regards,

I was able start the service twas-zookeeper.

twas-zookeeper.service - ThingWorx Analytics - Zookeeper
   Loaded: loaded (/etc/systemd/system/twas-zookeeper.service; enabled; vendor preset: enabled)
   Active: active (running) since Mi 2018-10-24 08:22:27 CEST; 20s ago

But the problem still exists. I am also getting the error message, when I try to use other twas microservices like CreateModelAMS:

[message: Execution error in service script [CreateModelAMS] :: Error returned from service [500]: Failed during training

The error was caused by sufficient folder permission. The related error message was logged in the /opt/twxanalytics/data/logs/data.log
