-------------------------------------
Summary: 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
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).
