Subject Error Running Gridgain's LoadCaches java application
Date Fri, 24 May 2019 16:57:10 GMT
Hello, very new to Ignite and excited about using the application.  I have
installed one Apache Ignite 2.7 node on a GCP VM.  I have the web agent
running locally and I am using Gridgain's Web Console.  I am getting an
error trying to run the LoadCaches java application that the Gridgain Web
Console generated based on my MySQL database.  

Logs from Ignite Server:
