I had this exact problem on my M1 Mac Mini. Here are the steps I took to solve it.
Reinstall Surreal DB:
brew reinstall surreal
Reboot:
Just in case...
Open a terminal window and start tiup:
tiup playground --tag surrealdb --mode tikv-slim --pd 1 --kv 1
Open another terminal window and start SurrealDB:
surreal start --log debug --user root --pass root memory
Hope this helps.

I'm completely mystified by this. AFAICT this is something AppEngine does internally so I don't think I have any way to debug this further? FWIW, my app is super simple ATM:
module xyz
go 1.17
require (
github.com/go-chi/chi/v5 v5.0.7
go.etcd.io/bbolt v1.3.6
google.golang.org/appengine/v2 v2.0.1
)
require (
github.com/golang/protobuf v1.3.1 // indirect
golang.org/x/sys v0.0.0-20200923182605-d9f96fdee20d // indirect
)
And:
runtime: go116
main: ./cmd/server
The solution was to go to container registry (maybe artifact registry soon) in the cloud console and delete all the containers there. The issue was quite likely just one of those images (maybe the build cache one) but my app is not released so I could just delete all of them.
I resolve it using --no-cache option, but its not perfect because cache is not enabled.
$ gcloud app deploy app.yaml --no-cache
Using the following installation on Ubuntu Server 20.04 :
sudo apt-get update
sudo apt-get install nodejs
sudo apt install python2
sudo apt install npm
npm install ganache-cli
npm install node-gyp#3.6.2
npm install truffle#5.1.39
sudo npm install create-react-app#3.3.1 -global
npm install
I am having the error
Failed to load resource: net::ERR_CONNECTION_REFUSED 127.0.0.1:8545/:1
I am running ganache with the command line interface:
I can test the connection via node command prompt
To which I am able to verify a connection to ganache private blockchain
Then I try App.js in React
obtaining the following error:
I have tried the following:
1.) Setting up a proxy under package.json : http://127.0.0.1:8545
2.) Trying http://0.0.0.0:8545
3.) Setting up a middleware proxy account as presented in the following solution:
https://medium.com/bb-tutorials-and-thoughts/react-how-to-proxy-to-backend-server-5588a9e0347
"proxy": "http://127.0.0.1:8545"
4.) addressing cache related issues through rm -r package-lock.json node_modules and npm install updating react.js to latest version
5.) trying different port: 7545
6.) updating react to latest version on ubuntu
I figured it out - thanks to all who reviewed my problem. - hopefully this will help someone in the same situation. To connect to an ec2 instance with React.js / blockchain dapp you need to follow five steps:
1.) set appropriate security rules (you will need to allow access for an instance to reach your server) I set the following rules in a very liberal fashion since this was only a test:
you need to start ganache with explicit chainId specified and a direct reference to your public domain IPv4 DNS domain e.g (
http://ec2-54-186-149-26.us-west-2.compute.amazonaws.com)
the command should look as follows:
3.) the same domain mnemonic needs to be specified in metamask (along with an imported account from your ganache server ) It should look as follows:
4.) React.js also needs to access the domain from EC2 directly (do not use localhost ,even you are running on the server the loopback will not work! - also do not use a shortcut with or (||) condition as that also produced errors for me ). It should look similar to below:
5.) your smart contracts also need this domain specified explicitly - so you will also need to edit your truffle-config.js as follows:
Finally i can read my blockchain via React.js on a test network (ganache) via EC2.
Below is blockchain data presented to screen.
I hope this helps someone out there - this was not found easily.

I am new to flink and trying to deploy my jar on EMR cluster. I have used 3 node cluster (1 master and 2 slaves) with their default configuration. I have not done any configuration changes and sticking with default configuration. On running the following command on my master node:
flink run -m yarn-cluster -yn 2 -c Main /home/hadoop/myjar-0.1.jar
I am getting the following error:
INFO org.apache.flink.yarn.YarnClusterDescriptor- Deployment took more than 60 seconds. Please check if the requested resources are available in the YARN cluster
Can anyone please explain what could be the possible reason for this error?
As you didn't determine any resources (Memory, CPU core), I guess it's because the YARN cluster has not the desired resource, especially memory.
Try submitting your jar file using the following type of commands:
flink run -m yarn-cluster -yn 5 -yjm 768 -ytm 1400 -ys 2 -yqu streamQ my_program.jar
You can find more information about the command here
You can check application logs in YARN WebUI to see what's the problem exactly.

I am using 5 cloud-based VMs to install DC/OS
1 mesos master
3 mesos agent
1 launching VM
I have installed Docker on my launching VM and start installing DC/OS. It is running successfully during install_prereqs stage without any errors. But it's failing during preflight with below errors for each of my VM system.
STDERR:
Connection to 129.114.18.235 closed.
STDOUT:
Running preflight checks /opt/dcos_install_tmp/dcos_install.sh: line 225: getenforce: command not found

Checking Docker is configured with a production storage driver: /opt/dcos_install_tmp/dcos_install.sh: line 285: docker: command not found
Do I need to install all the required software into my master and agents VMS? Please guide.
We have a similar setup but using straight vm's. We found docker needs to be running on all nodes, including masters, before running the install. Also, make sure you look at: /etc/sysconfig/docker-storageand have: DOCKER_STORAGE_OPTIONS= -s overlayset in the file on all nodes.
I don't believe this is the production setup but should get you running. You also may want to check the privilege of the user executing the install on the remote nodes, does it have permission to see/run systemctl?
I had the same error with the DC/OS web installer in version 1.9
I solved the error after double-checking the bootstraps machines's private key in the web form. To create the key, log into the bootstrap machine and run:
$ ssh-keygen -t rsa
$ for i in `cat dcos-ips.txt`; do ssh-copy-id root#$i; done
$ cat ~/.ssh/id_rsa

Deploy
Deploy also doesn't work. Fails because of timeout.
gcloud preview app deploy ./app.yaml
WARNING: Soon, deployments will set the deployed version to receive all traffic by
default.
To keep the current behavior (where new deployments do not receive any traffic),
use the `--no-promote` flag or run the following command:

To adopt the new behavior early, use the `--promote` flag or run the following

$ gcloud config set app/promote_by_default true
Either passing one of the new flags or setting one of these properties will
