-------------------------------------------
Summary: Prepare and finish future never time out
Key: IGNITE-2797
URL: https://issues.apache.org/jira/browse/IGNITE-2797
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 1.5.0.final
Reporter: Valentin Kulichenko
Priority: Blocker
Fix For: 1.6
Even if transaction timeout is configured, transaction will not timeout if it's
already in prepare state. It will be shown in log as pending transaction and
can cause the whole cluster hang.
We need to add a mechanism that will properly timeout prepare and (if possible)
finish futures.
Also we can create an event that will be fired if there is a transaction
pending for a long time, showing which nodes we are waiting responses from.
This will allow user to recover by stopping only these nodes instead of
restarting the whole cluster.
