QUESTION
I am trying to install PySpark package Graphframes using spark-shell :
...ANSWER
Answered 2021-Jun-11 at 16:27The jar has to be downloaded from repos.spark-packages.org
. Unfortunately this repo is not checked by pyspark
when using the --packages
parameter. If your machine has a running Maven installation available, the easiest way to solve the problem is to manually download the jar to your local Maven repository:

The fetch api in addEventListener(click) only works once.

...ANSWER
Answered 2021-Jun-11 at 05:28Fetch is asynchronous, so it might be still running while the for loop is also running. You can turn the for loop into a while function.
QUESTION
Hey guys I am trying to run Quart in production.
That is my code: setups.py
...ANSWER
Answered 2021-Jun-09 at 20:47The app
instance on the server
module only exists when you invoke that module as the main module, which Hypercorn does not do. Instead you can invoke the factory function, hypercorn "server:create_app()"
.
You will likely want to move the db.init_app(app)
line to within the create_app
function (which I think you've called get_app_instance
?) as it is also only called if you invoke server as the main module.
I don't think you need __package__ = 'nini'
, which may also cause an issue.
QUESTION
I am fighting it the whole day. I am able to install and to use a package (graphframes) with spark shell or a connected Jupiter notebook, but I would like to move it to the kubernetes based spark environment with spark-submit. My spark version: 3.0.1 I downloaded the last available .jar file (graphframes-0.8.1-spark3.0-s_2.12.jar) from spark-packages and put it to the jars folder. I use a variation of standard spark docker file to build my images. My spark-submit command looks like:
...ANSWER
Answered 2021-Mar-22 at 12:12Okay, I solved my issue. Not sure whether it is going to work for other packages, but it lets me run graphframes in the mentioned setup:
- Download the latest .jar file from spark-packages
- Remove version-part of its name, leaving only the package name. In my case it was:

Answered 2021-May-08 at 21:48your classNames
were not getting build properly that is why you were getting index out of range.
for example, you got class id as 47(which is a cup) but an entry for 46(classid -1) was not present in classNames.
so the fix would be:
QUESTION
I only want to allow access to my server from one domain. Lets say my domain is called "mydomain.mydomain.com" (yes, it is a subdomain).
Normally I would write everywhere server_name mydomain.mydomain.com, but I changed it to a non-existing domain and I can still enter the website? Why is my website working also from other domains? I know nginx is normally using the first server-block if no server_name is found, but my first server-block is my catch-all non-existing domain block. I defined server_name _;
and default_server
, but still, my website is working.
I have the following configuration:
...ANSWER
Answered 2021-Apr-19 at 04:34You are listening to the IpV6 network socket in your server blocks where you change domain to non-existent. Since there are no other such server blocks, they are the default for those IPv6 ports.
Note that your first server block is default only for IPv4 network socket listen 80 default_server;
.
Thus the behavior can be explained only by the fact that you are connecting/testing over IpV6.
To avoid inconsistency, use default_server
for all your listen options. E.g. in the first server block add default server for IPv6 too:
QUESTION
Situation:
- I have many (not defined number) web applications (app1 with the URI "/app1" and app2 with the URI "/app2") that listen the port 80 on the same machine and with the same server_name in configuration files.
- There is the automation tool that manages the configuration files for each project absolutely separately. Thus I need two different configuration files.
- If I try to include
server
directives with the samelisten
andserver_name
directives expecting the concatenation of the servers (all directives from the servers works like they are located in one server, I will get the warningnginx: [warn] conflicting server name "some_server_name" on 0.0.0.0:80, ignored
and one of the servers will be ignored. - One can say "just put
location /app1 {...}
into app1.conf ,location /app2 {...}
into app2.conf, ... , then include this confs into oneserver
directive". But it is not an option because I need ownmap
directives for each app andmap
directives cannot be incorporated intoserver
directive. - I cannot use different server_name because it is already with a third-level domain and a fourth-level domain is not really an option.
Question: how to achieve the described "concatenation"?
...ANSWER
Answered 2021-Apr-16 at 07:06I came up with two ideas
First idea: Separate configuration parts (Not usual view, no isolation)Inner-server
and an outer-server
directives can be put into two other files.
No isolation problem appears here as a problem of overwriting things from app1 by app2 and alerting with errors for not overwritable things.
Note: The example below is only for simple demonstaration and not actual practice.
