[jira] [Created] (IGNITE-9663) MVCC: Data node failure can cause TX
hanging.
Andrew Mashenkov created IGNITE-9663:
----------------------------------------
Summary: MVCC: Data node failure can cause TX hanging.
Key: IGNITE-9663
URL: https://issues.apache.org/jira/browse/IGNITE-9663
Project: Ignite
Issue Type: Improvement
Components: cache, mvcc
Reporter: Andrew Mashenkov
Fix For: 2.7
Next test hangs due to a bug:
CacheMvccTransactionsTest.testPutAllGetAll_ClientServer_Backups1_Restart_Scan
Possibly, it is caused with a race in MvccTracker and can be partially fixed in [#1] or
we have a bug in TX mapping in enlist phase on unstable topology.
I've tried to avoid races in Tracker and see TX hanged awaiting PME that version has just been completed. This need to be investigated.
