Summary: Incorrect detection of multiple grid instances Key: IGNITE-15334 URL: https://issues.apache.org/jira/browse/IGNITE-15334 Project: Ignite Issue Type: Bug Affects Versions: 2.9.1 Reporter: Sergey Kadaner The IgnitionEx class has a validation that checks if SPI supports multiple grid instances. However, the following code is used to check if it is a single instance: {code:java} startCtx.single(grids.size() == 1); {code} In my case the grid size is zero, therefore startCtx.single is false which triggers an error for SPI that does not support multiple instances. IMHO the the following code should be used instead: {code:java} startCtx.single(grids.size() < 2);{code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
