[jira] [Updated] (IGNITE-7648) Fix IGNITE_ENABLE_FORCIBLE_NODE_KILL
system property.
[ https://issues.apache.org/jira/browse/IGNITE-7648?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexei Scherbakov updated IGNITE-7648:
--------------------------------------
Description:
IGNITE_ENABLE_FORCIBLE_NODE_KILL system property was introduced in IGNITE-5718 as a way to prevent unnecessary node drops in case of short network problems.
I suppose it's wrong decision to fix it in such way.
We had faced some issues in our production due to lack of automatic kicking of ill-behaving nodes (on example, hanging due to long GC pauses) until we realised the necessity of changing default behavior via property.
Right solution is to kick nodes only if failure threshold is reached. Such behavior should be always enabled.
UPDATE: During a discussion it was decided what the property will remain disabled by default.
