Vyacheslav Koptilin resolved IGNITE-11559.
------------------------------------------
Resolution: Won't Fix
This is not actual anymore due to IGNITE-13871, IGNITE-15760
> MVCC: Tx hangs on finish if StorageException occurs.
> ----------------------------------------------------
>
> Key: IGNITE-11559
> URL: https://issues.apache.org/jira/browse/IGNITE-11559
> Project: Ignite
> Issue Type: Bug
> Components: mvcc, persistence
> Reporter: Andrey Mashenkov
> Priority: Major
> Labels: WAL, mvcc_stability, transactions
>
> By default non-mvcc transactions don't log their states in WAL log, so tx
> rollbacks without hanging as there is nothing to save to WAL or PageMemory.
> So, it may be helpful to check case for non-mvcc tx with txState WAL-logging
> enabled at first.
> When StorageException occurs during any mvcc tx operation enabled, then
> storage locks become blocked. Then Ignite try to rollback Tx due to the error
> and try to save txState into WAL and TxLog and hangs forever. A thread hangs
> awaiting uninterruptibly for next WAL segment or lock released.
> Failure handler tries to stop a node and hangs as well.
> Looks like we shouldn't wait if kernal context become invalid.
> Good startpoint is IgniteWalFlush* tests.
