             Summary: Cluster locks after the transaction recovery procedure if the tx primary node fail
                 Key: IGNITE-17457
                 URL: https://issues.apache.org/jira/browse/IGNITE-17457
             Project: Ignite
          Issue Type: Bug
            Reporter: Sergey Korotkov


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}
