Thrift Connection refused
Hi,
I followed the step of Ubuntu Open Source GPU with Tarball to install Omnisci on Ubuntu GPU instance.But when I wanted to load some sample data and perform an omnisql query, I encountered some mistakes as below:
I ran the code
shell
cd $OMNISCI_PATH
>sudo ./insert_sample_data
When prompted, I entered 2 to insert the 10 thousand row flights dataset. But the output was like this:
-adding schema Thrift: Fri Jan 29 21:54:51 2021 TSocket::open() connect() : Connection refused Thrift: Fri Jan 29 21:54:51 2021 TSocket::open() connect() : Connection refused Failed to open transport. Is omnisci_server running?
Then, I ran the following code:
shell
$OMNISCI_PATH/bin/omnisql
After I input the password, it outputs
Thrift: Fri Jan 29 22:08:16 2021 TSocket::open() connect() : Connection refused Thrift: Fri Jan 29 22:08:16 2021 TSocket::open() connect() : Connection refused Failed to open transport. Is omnisci_server running?
It seems I can't connect to the server, but the server is already running
omnisci_server.service - OmniSci database server Loaded: loaded (/lib/systemd/system/omnisci_server.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2021-01-29 22:42:34 CST; 673ms ago Main PID: 45979 (omnisci_server) Tasks: 7 Memory: 14.8M CPU: 425ms CGroup: /system.slice/omnisci_server.service └─45979 /opt/omnisci/bin/omnisci_server --config /var/lib/omnisci/omnisci.conf
My system is Ubuntu 16.04, and I use 8 Tesla V100-PCIEs as my gpu. There are some schoolfellows using these gpus too, does this affect?
Thanks!

Hi @earyj,
Welcome to the community forum ;)
Obviously, the server isn't running, or it's not running on the default port (6274), or there is some other issue.
The Tesla V100-PCI-E works flawlessly with our database, so that the problem could be in the driver (or in the combo Driver and OS)
The service status looks the server has started since 673ms only, so maybe it's crashed and restored by the system.
You can try to stop the service and start from the command line.
sudo service omnisci_server stop /opt/omnisci/bin/omnisci_server --config /var/lib/omnisci/omnisci.confCheck if there are some errors, and please report back.
You can also try to tea a look at the log files that are located under /var/lib/omnisci/mapd_logs and check for the latest

Sorry for replying late.
My fault. I didn't read the requirements carefully. The output of
nvidia-smiis as below
So it seems that the mistake is because the driver and cuda version don't meet the requirements. But I can't upgrade them as there are others using the server in the meantime.
I want to use the former MapD version that matches the driver version. Though I do find the documents of the former release, the download link always points to the latest version :joy:
May I aquire the fomer CE version?

@earyj,
Don't worry.
I will provide a link to the newest OS version that would run with such old driver; It's the 5.1.2. Quite old, but new enough to get you an idea about the software.
you can download at this link
or If you prefere you can install the same version using apt (but I'm not sure if you have administrative privileges, and they are needed to do that)
