> Key: IGNITE-17457
> URL: https://issues.apache.org/jira/browse/IGNITE-17457
> Project: Ignite
> Issue Type: Bug
> Reporter: Sergey Korotkov
> Assignee: Sergey Korotkov
> Priority: Major
>
> Ignite cluster may be locked (all client operations would block) after the tx
> recovery procedure executed on the tx primary node failure.
> The prepared transaction may remain un-commited on the backup node after the
> tx recovery. So the partition exchange wouldn't complete. So cluster would
> be locked.
> The Immediate reason is the race condition in the method:
> {code:java}
> org.apache.ignite.internal.processors.cache.transactions.IgniteTxAdapter::markFinalizing(RECOVERY_FINISH){code}
> It may be called concurrently for the same transaction both from the recovery
> procedure:
> {code:java}
> IgniteTxManager::commitIfPrepared{code}
> and from the tx recovery request handler:
> {code:java}
> IgniteTxHandler::processCheckPreparedTxRequest{code}
>
> Details and reproducer {color:#ff0000}TBD{color}
