----------------------------------------
Also, please make sure the log message is understandable to the average user to
avoid cases like this: https://issues.apache.org/jira/browse/IGNITE-6716
> Need to validate nodes configuration across cluster and warn on different
> parameters value

> Key: IGNITE-8951
> URL: https://issues.apache.org/jira/browse/IGNITE-8951
> Project: Ignite
> Issue Type: Task
> Reporter: Yakov Zhdanov
> Priority: Major
>
> On node start, node should output in its logs the list of parameters havnig
> values different from values on remote node. This should be skipped for
> parameters that are always different e.g. host name, node ID or IP, however
> should be an option to include parameters from default ignore list as well.
> Another requrement is that the intended output may be fully supressed by
> setting sysmem property -DIGNITE_SKIP_CONFIGURATION_CONSISTENCY_CHECK=true
> It seems that the implementation approach should be similar to performance
> suggestions Ignite currently has.
> The output may be as following
> {noformat}
> Local node has different configuration comparted to remote nodes for
> paramenters (fix if possible). To disable, set
> -DIGNITE_SKIP_CONFIGURATION_CONSISTENCY_CHECK=true
> ^-- rebalanceThreadPoolSize [locNodeVal=4, rmtNodeId=X1X1, rmtNodeVal=8]
> ^-- commSpi.selectorsCnt [locNodeVal=2, rmtNodeId=Y1Y1, rmtNodeVal=4]
> ^-- commSpi.selectorsCnt [locNodeVal=2, rmtNodeId=Z1Z1, rmtNodeVal=8]
> {noformat}
> All components should add messages to {{cfgConsistencyRegister}} on startup
> and then all differences should be output in one step.
> If node aborts startup due to any problem differences collected so far should
> be output to logs.
> If there are more than 1 value for some config parameter among remote nodes
> then all distinct options should be output (see {{commSpi.selectorsCnt}} in
> the example above).
