this is the manifest i have used for creating for kafka:

...ANSWER
Answered 2021-Oct-19 at 09:03Your Kafka and Zookeeper deployments are running in the kaf namespace according to your screenshots, presumably you have set this up manually and applied the configurations while in that namespace? Neither the Kafka or Zookeeper YAML files explicitly state a namespace in metadata, so will be deployed to the active namespace when created.
Anyway, the Kafka deployment YAML you have is hardcoded to assume Zookeeper is setup in the default namespace, with the following line:
QUESTION
I have a Reactor Kafka application that consumes messages from a topic indefinitely. I need to expose a health check REST endpoint that can indicate the health of this process - Essentially interested in knowing if the Kafka receiver flux sequence has terminated so that some action can be taken to start it. Is there a way to know the current status of a flux (completed/terminated etc)? The application is Spring Webflux + Reactor Kafka.
Edit 1 - doOnTerminate/doFinally do not execute
...ANSWER
Answered 2021-Oct-12 at 07:57You can't query the flux itself, but you can tell it to do something if it ever stops.
In the service that contains your Kafka listener, I'd recommend adding a terminated (or similar) boolean flag that's false by default. You can then ensure that the last operator in your flux is:

After installing anaconda on my windows 10 machine, and then I followed the following tutorial to set it up on my machine and run it with jupyter : https://changhsinlee.com/install-pyspark-windows-jupyter/

ANSWER
Answered 2021-Jun-23 at 19:42Similar error (and same answer) - Spark Kafka Data Consuming Package
Did you literally write ... after the --packages option?
The error is telling you to give a .py file or --class along with a JAR file containing your application code
And if you did give one, then it would seem the Spark user cannot access the D:\ drive path that you gave, and you likely need to use winutils chmod to modify that
If you want to run the code in Jupyter, you can add --packages there too

I built the Apache Oozie 5.2.1 from the source code in my MacOS and currently having trouble running it. The ClassNotFoundException indicates a missing class org.apache.hadoop.conf.Configuration but it is available in both libext/ and the Hadoop file system.
I followed the 1st approach given here to copy Hadoop libraries to Oozie binary distro. https://oozie.apache.org/docs/5.2.1/DG_QuickStart.html
I downloaded Hadoop 2.6.0 distro and copied all the jars to libext before running Oozie in addition to other configs, etc as specified in the following blog.
https://www.trytechstuff.com/how-to-setup-apache-hadoop-2-6-0-version-single-node-on-ubuntu-mac/
This is how I installed Hadoop in MacOS. Hadoop 2.6.0 is working fine. http://zhongyaonan.com/hadoop-tutorial/setting-up-hadoop-2-6-on-mac-osx-yosemite.html
This looks pretty basic issue but could not find why the jar/class in libext is not loaded.
- OS: MacOS 10.14.6 (Mojave)
- JAVA: 1.8.0_191
- Hadoop: 2.6.0 (running in the Mac)
ANSWER
Answered 2021-May-09 at 23:25I was able to sort the above issue and few other ClassNotFoundException by copying the following jar files from extlib to lib. Both folder are in oozie_install/oozie-5.2.1.
- libext/hadoop-common-2.6.0.jar
- libext/commons-configuration-1.6.jar
- libext/hadoop-mapreduce-client-core-2.6.0.jar
- libext/hadoop-hdfs-2.6.0.jar
While I am not sure how many more jars need to be moved from libext to lib while I try to run an example workflow/job in oozie. This fix brought up Oozie web site at http://localhost:11000/oozie/
I am also not sure why Oozie doesn't load the libraries in the libext/ folder.

I was using an older Kafka version.
I upgraded Kafka in the cluster from kafka_2.12-1.1.0 to the latest stable version kafka_2.12-2.7.0. I also upgraded zookeeper from zookeeper-3.4.6 to apache-zookeeper-3.6.2-bin version.
