QUESTION
I'm trying to run a Structured Streaming program on GCP Dataproc, which accesses the data from Kafka and prints it.
Access to Kafka is using SSL, and the truststore and keystore files are stored in buckets. I'm using Google Storage API to access the bucket, and store the file in the current working directory. The truststore and keystores are passed onto the Kafka Consumer/Producer. However - i'm getting an error

QUESTION
I've a simple Structured Streaming program, which reads data from Kafka, and writes on the console. This is working in batch mode (i.e spark.read or df.write), not not working in streaming mode.

...ANSWER
Answered 2022-Feb-02 at 09:28Structured Streaming is trying to checkpoint to the properly set "checkpoint" directory but seems like the job itself has no right to do that. If checkpoint is not working then it's totally valid that the workload is stopped and not progressing.
Please double check why Hadoop FS is not able to be written and re-run the workload. Just a hint, maybe one can use full path when setting "checkpointLocation" to be more explicit which directory to use.
QUESTION
I'm creating a Dataproc cluster, and it is timing out when i'm adding the connectors.sh in the initialization actions.
here is the command & error
...ANSWER
Answered 2022-Feb-01 at 20:01It seems you are using an old version of the init action script. Based on the documentation from the Dataproc GitHub repo, you can set the version of the Hadoop GCS connector without the script in the following manner:
QUESTION
I have a macOS web browser made using SwiftUI and WebKitView that works well with most sites but some pages such as WhatsApp i get the following error message to upgrade to a newer version of safari.
WebView
...ANSWER
Answered 2021-Sep-21 at 13:27First of all you can use Safari Services instead of WKWebView, so you will be actually using a compatible browser.
Otherwise, it depends how the site checks the browser it's loaded in.
The most primitive way to check the browser type and version, is to look at browser's user agent string. For cases like this, you may be able to surpass the check by setting a customUserAgent on WKWebView to whatever the site supports. It's a hack though, as your WKWebView pretends to be a different browser.
More sophisticated cases check not the actual browser, but the capabilities they need. For example the site may check if cookies, or local storage is enabled. In this case you should just enable the required capabilities on your WKWebView.
In third case, site tries to explicitly block embedding its content into WKWebView or WebView. In that case you have to respect the site owner wishes, and not try to embed the site.
Which one is the case of WhatsApp, not quite sure. You will have to experiment I guess.
QUESTION
It all happened with when I changed the main()
in main.dart
to async
function for sqflite
package.
When I run the app Chrome opens for debugging but shows a whole white empty screen and in the Visual Studio Code a file named web_entrypoint.dart
opens showing this line:
Here is the main() inside the main.dart:
...ANSWER
Answered 2021-Feb-26 at 11:43sqflite has no support for the web. Not only is the tag missing from the package, it even directly says so:
Other platforms support:
- [...]
- Web is not supported.
So whatever causes your exact problem, you won't be able to use the database this way anyway. Chances are, what you see is the result of this.
