Hi everyone !
Could you please help? I've set up a schedule for the launch plan in my project. Question: How to prevent the new launch plan execution if the previous one still running ?
I try to find such option in the source code but I can't found. The concurrent execution of the job is unacceptable for my use case.
T... | currently it is not possible to do this - could you open up a github issue in the flyte repo please?
could you also describe the use-case/why you want to do this? context always helps.

Hi. I’m working on flytepropeller plugin. Just a quick question here: am I supposed not to have an access to kubeClient or there is a way to use it?
| Hey Igor Valko :wave:
To clarify your question. Are you asking if your plugin will have a client so that you can can create and watch k8s resources? If so, the answer is yes, your plugin should have access to that.

Almost certainly memory/cpu I think. Heres what I am noticing. my k8s cluster has spun up on the order of 30 sync resources pods that seem to be stuck in pending state. My guess is that is what is going wrong.

I'd like more details on the debugging side. I'd assume that most of the time people are just logging what seems to be important. When something goes wrong, they look at the output and add extra prints to chase down the issue.

| Here is something I do in personal projects sometimes:
I place my task logic in a separate python module. My Flyte workflow mostly handles passing the inputs to those module functions.

Does it matter what order you stack the decorators in flytekit? In other words could you specify inputs, outputs, and python_task in any order?
| the task decorator needs to come before, but no order for inputs/outputs. you might even be able to apply input and output decorators multiple times.

Hi :hand:
Do you have experience running flyteadmin in multiple replicas? considering if we have enabled workflow scheduling and notifications.
Thank you in advance!

We run several Admin services (or replicas/pods) always. Admin is stateless. Workflow schedules and notifications should all work independent of the replica size.

Hello Everyone!
Does anybody work with Dynamic tasks? I'm trying to run dynamic tasks sequentially, but it always runs in parallel even I set `max_concurrency=1`
The sample workflow:
```from __future__ import absolute_import, division, print_function
from flytekit.sdk.tasks import dynamic_task, inputs, outputs, python... | Yee / Haytham Abuelfutuh if you near a computer. Else I will answer in a bit

Hey Aleksandr, yes max concurrency is not yet implemented unfortunately. However, you can achieve what you want by generating a workflow with node dependencies between the nodes in the `@dynamic_task` . Let me try to write you an example:

Haytham Abuelfutuh could you share any timelines when `max_cuncurrency` can be implemented?

| hi Aleksandr Vergeychik can you please file an issue or +1, if there is one. I think someone is looking into this. Lets use that forum

I’m trying to run Spark tasks to run in a Flyte sandbox installation but I’m running into issues. I managed to configure everything so that Flyte starts the driver pod but now I’m stuck with the following error (from the pod logs):
```Usage: entrypoint.py [OPTIONS] COMMAND [ARGS]...
Try 'entrypoint.py --help' for help.... | Sören Brunk (in a meeting) will brb

| hi. this is installed by flytekit <https://github.com/lyft/flytekit/blob/eec85fb35e5dd975840aa0019dfdc167af1e4f29/setup.py#L55>
so please make sure in your pip requirements file that you install `flytekit[spark]` or better yet `flytekit[all]` instead of just `flytekit`

| Yee thanks. Yes I’m installing `flytekit[spark]` (haven’t tried `flytekit[all]` yet.
Essentially, I’ve taken the <https://github.com/lyft/flytesnacks/blob/master/python/Dockerfile|Dockerfile of the python example from flytesnacks>, then I’ve added these lines:
```RUN ${VENV}/bin/pip install flytekit[spark]

| Same error ( I have to add `. ${VENV}/bin/activate` to flytekit_spark_entrypoint.sh in this case because I otherwise I can’t register tasks).

| Anmol Khurana can probably provide the most context here. but i believe the way spark assumes entrypoints wreaks havoc on venvs. i would suggest the following:
1. make `ENTRYPOINT ["/opt/flytekit_spark_entrypoint.sh" ]`
2. then make an executable script of your own which activates venv and then passes along the args. ... |
