--------------------------------------
Summary: 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
Fix For: 2.7
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.
