This line : ELASTICSEARCH_HOSTS: httelasticsearch:9200
change to: ELASTICSEARCH_HOSTS: http://elasticsearch:9200/

Grafana
in the script runWithFlinkEspBoard.sh,
the line ./run.sh "${@}" & are not working,
change to: /run.sh "${@}" &

Menu layout does not work on narrow displays.

java.lang.IllegalArgumentException: ProcessConfigCreator not found. Jars found: file:/E:/gits/nussknacker-master/ui/server/../../engine/flink/management/sample/target/scala-2.11/managementSample.jar

Hi,

I just cloned the repo and wanted to start working with the demo setup. Unfortunatelly I run in to a problem when adding a new process to Nussknacker:

[ERROR] [06/19/2019 10:20:51.613] [nussknacker-ui-akka.actor.default-dispatcher-35] [akka.actor.ActorSystemImpl(nussknacker-ui)] Error during processing of request: 'No configuration setting found for key 'kafka.zkAddress''. Completing with 500 Internal Server Error response. To change default exception handling behavior, provide a custom ExceptionHandler.

I started looking for causes and found out that just 4 hours ago a commit was made:

"[CONFIG] - remove unused zkAddress config" by mproch
f803ae3

Could it be that zkAddress was used?

Thanks,
Marek

Some windows are quite large. When they cover diagram, you lose some context e.g. can not quick check where in the diagram they are.

(react-draggable?)

Please consider showing some process metrics (tx/last minute, hour, day, last event) on the main process list. They would help easily check process health.

It's a good feature but I think its UX should be redesigned (not consistent icon, not visible).

Hi.

I'm running docker-compose up as it says in the quickstart guide, however it seems to have an issue with starting the nussknacker service properly. Kibana , grafana and flink web services are up and running , but nussknacker returns 502.

I'm not sure, but I belive it has something to do with Error that comes up when I run docker compose.
The log below just repeats itself until I "ctrl+c" it :)

I tried fixing this with substituting flink-metrics-graphite-1.2.0.jar with the newer flink-metrics-graphite-1.6.0.jar, but it didn't help :)

How can I solve it?

Now categories are assigned to each objects (sources, sinks, services, custom nodes, globalVariables etc.) in relation one to many. This design choice causes that some configurations are hard to achieve e.g.:

• For one category you can't have global variable with other fields than in other one
• If you want to have object executed in runtime differently according to category, you need to create many such objects with other ids (see #122)

I think that api should be redesigned that categories should be a root objects for others. Process in runtime should have information of category and should create extensions based on it.

Describe the bug

Expected behavior
No such warnings

Hi there,

I am taking a look at composability of the designer, can you clarify what subprocesses are, their behavior etc?

Thank you!

Hi, I have several errors when I try to compile "ui" via "buildServer.sh" or "build.sbt".

In order the problems i encounter are :

2. I tried to update package.json to avoid this, but without any postive response.

Expression code completion should be proposed automatically, as new users won't be aware of the feature.

Bug information
When we set on configuration flinkConfig.queryableStateProxyUrl and taskamanger service is unavaiable then application throws error and doesn't response.

To Reproduce

1. Disable in /demo/docker/docker-compose.yml two services: taskmanager and jobmanager
2. Run docker compose
3. Check nussknacker_app logs - see errors.

Expected behavior
Application should run normally even then taskmanager is not avaiable.

Environment:

• Nussknacker version: all
• Java version: 1.8
• Method of ran of components: docker demo example with disabled: taskmanager and jobmanager

Describe the bug
Menu layout does not work on a narrow screen.

Expected behavior
Menu should be visible regardless of the screen size.

I follow the quickstart after installing and running,
(https://touk.github.io/nussknacker/Quickstart.html)

but, I check:
Nussknacker failed {open link: http://localhost:8081/ return: 502 Bad Gateway}
Apache Flink ui ok
Grafana ok
Kibana ok

Who can help me?

regards,
Hai Zhou

Describe the bug
For user, on the list of processes are visible all processes - even if he/she hasn't got configured Read permission for some category.

To Reproduce
Steps to reproduce the behavior:

1. Having Flink and Nussknacker ran e.g. in docker with configured two categories: one visible for user A and the second not visible.
2. Open browser, login as a user A and go to 'main page'

Expected behavior
User A should see processes in categories that he/she has Read permission,
, but:
User A see all processes.

Add documentation for:

• subprocesses
• custom transformers
• ....

It would be useful to add service description metadata in the code and show it later in NN.

hi~ ,i am not familiar with Scala，can u explain it more specifically about Engine is a library which transforms json representation of graph with Nussknacker process into Flink job.

1. what is framework of the json representation of graph?
2. how to transform the json to flink job?

thks !

Common use of "align" is to align several selected items in some way. I think this button shoud be renamed to "layout".

Hi there!

Thank you for this amazingly thought-out project. I have just started experimenting with it, and I am already amazed with the kind of base/infrastructure your project can give in my use case. I am still experimenting, but I already forked the project to get myself more comfortable.

Because this issue is very minor in UI, I didn't want to open an issue first. But rather than keep a note for myself, I thought I'd add the things I see as I go along in the issue tracker.

The error from quickstart kit:

Uncaught TypeError: Cannot read property 'type' of undefined

    at d._renderValidatedComponentWithoutOwnerOrContext (bundle.js?be3ab410fce0434642f9:183)

Initial state:

Clicked "properties" on the right side:

You can see the console as well as query parameter on the URL = undefined.

Thank you again! It is going to be fun experimenting with nuss.

someone changed process X
no new events in process X for last hour
process X is stopped

Sample flow in docker example or on https://demo.nussknacker.io/ page would showcase capabilities of NN.

Now, visible name is used as a identifier in the process. Would be nice to have separated id and name for nodes visible on left panel. For example when in the app, there are two separate nodes for two categories, but we want to show it as a same node.

Describe the bug
On Firefox 69.0.1

To Reproduce
Steps to reproduce the behavior:

1. Run the demo

Expected behavior

Hello
run with docker compose it works for me up to the Save ( first process )

when i deploy the saved process i got an error in the docker logs
app_1 | org.apache.flink.util.ConfigurationException: Config parameter 'Key: 'jobmanager.rpc.address' , default: null (deprecated keys: [])' is missing (hostname/address of JobManager to connect to)
it seems related to
environment:
- JOB_MANAGER_RPC_ADDRESS=jobmanager in the docker compose file ...... ? right ?
one setting is lacking ?

best regards
philg

Should use VerboselyLoggingRestartingExceptionHandler

Clicking on Generate button shows a form and it allows for request the amount of test data. But the number is not validated and when I provide bla or 1000000000000000000000000000000000 then any error message is not shown. File is generated and contains only one line:

The requested resource could not be found.
