[jira] [Commented] (IGNITE-12151) Load Cache: Failed to load bean in app context

["Kurt Semba (Jira)" <ji...@apache.org>]

Kurt Semba commented on IGNITE-12151:
-------------------------------------

Hi all,

it seems that this was a misunderstanding on the overall workflow on my side. I got ignite to import data from my MySQL DB by running the cluster out of my IDE with the pre-built DB schema (using file ServerNodeSpringStartup.java). When run LoadCaches.java afterwards, it works fine. 

So in order to get my scenario to work I will have to provide the XML config file for my cluster in advance (at the point of startup). My impression was that I could create cache defintions on a running ignite cluster on the fly. But it seems that the cluster needs to be aware of all DB schemas it should talk to at the moment of startup.

Thanks

Kurt

>          Issue Type: Bug
>          Components: binary, cache
>    Affects Versions: 2.7.5
>         Environment: * Ubuntu 18.04
>  * Ignite server v2.7.5 - running in a docker container with the REST API module enabled
>  * Ignite web-console: 2.7.0 - also running in a docker container
>  * Ignite web-agent - downloaded from the web-console so I assume also using version 2.7.0 - not running in a docker container (properly connects to both the web-console as well as the cluster... until I kill my cluster ;) )
>  * MySQL DB: v5.7 running on a remote VM
>  * IDE: Visual Studio Code (latest update)
>            Reporter: Kurt Semba
>            Priority: Major
>         Attachments: Dockerfile, clientLoadCaches.log, cluster.log

> Hi team,
> I was following the instructions from  [https://www.youtube.com/watch?v=SJ6h55VhUBI] and onwards to use the web-console and web-agent to import data from a MySQL DB. It all works fine until I download the cluster configuration Java project from the web-console and try to run the "LoadCaches" java file in my IDE. 
> The client (LoadCaches code) fails with an "IgniteCheckedException: Failed to connect to node" exception but more importantly, the ignite cluster crashes as well with an "IgniteException: Failed to load bean in application context" exception. See both logs attached. 
> The parts where I diverged from the demo video series:
>  * I did not tweak the cluster config using the web-console - just kept it as it was auto-created by the web-console
>  * I edited  /src/main/resources/META-INF/ImportedCluster-client.xml and configured the IP of my Ignite cluster (both the ignite cluster and the IDE code are running on the same server, but using the default 127.0.0.1 didn't connect)
>  * I edited the pom.xml file to make the Java code use the latest v2.7.5 libraries to load the cache (since the cluster is also running this version)
>  
> Do I have to somehow pre-stage the cluster / cache with the DB table I'm trying to import? I was hoping that the web-console would do that when I use the "Import from Database" wizard?
> Maybe the version mismatch between web-console (2.7.0) and cluster (2.7.5) is an issue?
> Thanks
> Kurt
