Igor Seliverstov updated IGNITE-9470:
-------------------------------------
Priority: Major (was: Minor)
> MVCC TX: Mvcc transactions should throw proper exception when rolled back.
> --------------------------------------------------------------------------
>
> Key: IGNITE-9470
> URL: https://issues.apache.org/jira/browse/IGNITE-9470
> Project: Ignite
> Issue Type: Bug
> Components: jdbc, mvcc, odbc
> Reporter: Roman Kondakov
> Assignee: Ivan Pavlukhin
> Priority: Major
> Fix For: 2.8
>
>
> When MVCC transaction is rolled back due to a write conflict it throws
> {{CacheException}} with "Mvcc version mismatch" message. This behavior
> violates Ignite transactions API. Instead it should throw
> {{TransactionRollbackException}} with a clear message like a "Transaction has
> been aborted due to a write conflict (Please try again.)"
> It is also need to propogate this changes to JDBC and ODBC components and fix
> mvcc tests.
>
> In some tests we have to repeat tx operation in case of version conflict.
> Most likely, we can rely to caused-exception with some meaningful type (e.g.
> MvccVersionMismatchException) to repeat operation.
