-----------------------------------
Summary: OptimizeMakeChangeGAExample hangs forever with additional
nods in topology
Key: IGNITE-9359
URL: https://issues.apache.org/jira/browse/IGNITE-9359
Project: Ignite
Issue Type: Bug
Components: ml
Affects Versions: 2.6
Reporter: Alex Volkov
To reproduce this issue please follow these steps:
1. Run two nodes using ignite.sh script.
For example:
{code:java}
bin/ignite.sh examples/config/example-ignite.xml -J-Xmx1g -J-Xms1g
-J-DCONSISTENT_ID=node1 -J-DIGNITE_QUIET=false
{code}
2. Run HelloWorldGAExample from IDEA IDE.
*Expecting result:*
Example successfully run and completed.
*Actual result:*
There are a lot of NPE exceptions in example log:
{code:java}
