-----------------------------------
Summary: writeAsyncImpl doesn't cancel transactions in case of
errors
Key: RATIS-2433
URL: https://issues.apache.org/jira/browse/RATIS-2433
Project: Ratis
Issue Type: Improvement
Reporter: Abhishek Pal
Assignee: Abhishek Pal
Currently in RaftServerImpl#writeAsyncImpl() the client request is added to the
pending requests asynchronously.
In between if there is any failure/exception in appendTransactions() then we
are not cancelling the transaction. The failure is returned to the
client/retry-cache, but the statemachine is not notified.
This can cause partial state in the statemachine.
We should handle this such that in case of exceptions the statemachine is
notified via cancelTransaction().
