QUESTION
After configuring kafka connect using the official documentation...
I get an error that the driver does not exist inside the kafka connect!
I got to try copying the .jar
to the mentioned directory, but nothing happens.
Any suggestion for a solution?
docker compose
...ANSWER
Answered 2021-May-19 at 13:42The error is not saying your driver doesn't exist, it's saying the Connector doesn't. Scan over your error for each PluginDesc{klass=class
and you'll notice the connector.class
you're trying to use isn't there
The latest Kafka Connect images from Confluent include no connectors, outside of those pre-bundled with Kafka (and some ones from Control Center, which aren't really useful), so you must install others on your own - described here
If you want to follow the 5.0 documentation, use the appropriate tagged docker image rather than latest
(the old images do have the connectors installed)
Also, you would need to place the jdbc driver directly into the jdbc connector folder for it to properly be detected on the classpath; it is not a "plugin" in Connect terminology. The above link also shows an example of this

Answered 2021-Apr-23 at 12:54I have no idea what a yum is but I will assume that you're talking about YAML.
You can define a class attribute yaml_tag
to control the tag used when serializing your class. If you set it to the default tag for mappings, it won't be written:

I am trying out Deno with oak and I am running into the same error everytime - even when I try the default example. My working environment is macOs Big Sur. Does anybody know how to fix this issue?
...ANSWER
Answered 2021-Apr-18 at 10:18The error comes from incompatibility between deno earlier than 1.9 and oak later than v7.

QUESTION
I'm using Packer to build an ami with a file ami.json that runs two provisioners built off the default Ubuntu Server 20.04 LTS image. The problem is Packer build randomly fails on apt-get install ansible
with the error E: Unable to locate package ansible
. The same ami.json file builds or doesn't build intermittently despite zero changes.
It seems potentially related to this question from 5 years ago that got a workaround but not a real answer: Packer/Amazon EBS/Ubuntu - Inconsistent PPAs
...ANSWER
Answered 2020-Oct-06 at 13:16Try to add a 10 min sleep as the first provisioner. Ubuntu AMIs come with automatic updates on. So, whenever an instance is started, It will get updated itself.
QUESTION
I trying to write a Python script to convert the range between two IP addresses to CIDR,
...ANSWER
Answered 2020-Sep-02 at 19:01If iprange_to_cidrs
always returns the minimum number of IP ranges needed to span the supplied range (as seems likely) then you only need to test the length of the list which it returns.
However, if you do not want to verify that this is always the case, the following approach could be used.

...ANSWER
Answered 2020-Aug-05 at 15:41Yes, you're passing in each var in the list as an argument, aka 2 arguments. You can add each thread to a list, start them all, and then join them all which is generally how I use multiprocessing. Try something like this to give you an idea of how that might work--
