Following the instructions in https://beam.apache.org/documentation/runtime/environments/, when I build a custom container with the empty
Dockerfile mentioned, I get a "Fatal Python error: XXX block stack underflow" error in my stackdriver logs, and I cant figure out why. Any ideas? Thanks in advance!

My guess is that there's a Python version mismatch. What does
python3 --version give? Is it 3.8 like the container?
My problem is that the logs on the dataflow does not display anything (monitoring api is enabled) and I have no idea why.
With the following Apache Beam code (adopted from https://cloud.google.com/dataflow/docs/guides/logging),...

Turn out that the default sink in Logs Router exclude the Dataflow log.
Creating a new sink in Logs Router with inclusion filter of
resource.type="dataflow_step" fixes the problem.
I used a slightly modified version of the wordcount example (https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/wordcount.py), replacing the process function with the following:...

The standard Apache Beam example uses a very small data input:
gs://dataflow-samples/shakespeare/kinglear.txt is only a few KBs, so it will not split the work well.
Apache Beam does work parallelization by splitting up the input data. For example, if you have many files, each file will be consumed in parallel. If you have a file that is very large, Beam is able to split that file into segments that will be consumed in parallel.
You are correct that your code should eventually show parallelism happening - but try with a (significantly) larger input.
I have cloned the SCDF Kinesis Example: https://github.com/spring-cloud/spring-cloud-dataflow-samples/tree/master/dataflow-website/recipes/kinesisdemo and running the same. The kinesis Producer is running and publishing the events to kinesis. However, the Kinesis Consumer Spring Boot is failed to start due to the below ERRORS. Please let me know if anybody faced this issue and how to solve this?...

Check your configuration on credentials provided for the app as the error clearly says it failed due to "Status Code: 400; Error Code: AccessDeniedException"
I'm trying to modify the example sender in this Spring Cloud Stream tutorial to change the default sending interval.
The example was updated to use a functional
Supplier & removed the
@EnableScheduling\@Scheduled annotations, but I can't figure out how to change the schedule interval in the new version - this is what I tried unsuccessfully:

You need to provide poller configuration properties.
So, for your

I'm trying to do a custom build of "spring-cloud-dataflow-server:2.5.0.RELEASE" to add my Oracle driver. But it's failing. I have used the dependencies used for 2.2.0...

I just added new working build files for dataflow 2.5.x
I'm trying to run a Spring batch jar through SCDF. I use different datasource fpr both reading and writing(Both Oracle DB). The dataSource I use to write is primary datasource. I use a Custom Build SCDF to include oracle driver dependencies. Below is the custom SCDF project location.
I my local Spring batch project I implemented DefaultTaskConfigurer to provide my primary datasource. So when I run the Batch project from IDE the project runs fine and it reads records from secondary datasource and writes into primary datasource. But when I deploy the batch jar to custom build SCDF as task and launch it, I get an error that says,...

Instead of overriding the DefaultTaskConfigurer.getTaskDataSource() method as I have done above, I changed the DefaultTaskConfigurer implementation as below. I'm not sure yet why overriding the method getTaskDataSource() is causing the problem. Below is the solution that worked for me.
I've been trying out the SCDF for sometime with intention to use Oracle Database as datasource. Due to licensing issues Oracle driver has to be added to the classpath of SCDF server or we have to do a custom build of SCDF server with Oracle Driver dependency(Which I have). When I download the custom build project dataflow-server-22x (only this project) from github and try to execute I get a missing artifact issue in pom.xml as below....

Since you mentioned you don't run this on CloudFoundry and the specific dependency
io.pivotal:pivotal-cloudfoundry-client-reactor:jar comes from the
spring-cloud-dataflow-platform-cloudfoundry, you need to remove this dependency from the custom build configuration as below:
On spring cloud dataflow getting started page, (https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#spring-cloud-data-flow-samples-http-cassandra-overview)
It says run command below, but Error 404(Not found). wget https://repo.spring.io/snapshot/org/springframework/cloud/spring-cloud-dataflow-server/2.4.2.RELEASE/spring-cloud-dataflow-server-2.4.2.RELEASE.jar
as you can see, snapshot location and RELEASE version jar file.
This is not the only case, so I think there could be some reason.
I needs the meaning. Thanks...

Thanks for reporting it. This is indeed a bug in the data flow site configuration. This is fixed via:https://github.com/spring-io/dataflow.spring.io/issues/228 I will post an update once the fix is applied to the site.
