Burcu Ozkan updated RATIS-1048:
-------------------------------
Description:
I am testing fault tolerance of Ratis, more specifically whether it can
tolerate random message losses. Simply, I drop some of the messages and do not
deliver them to the recipient.
In some tests, I observe executions in which the Ratis servers cannot elect a
leader. The servers continuously start leader election but none of them succeed.
You can find the execution logs together with the list of exchanged and dropped
messages (the messages marked by "-D" are dropped) in the attachments.
> Ratis cluster fail to elect a leader when some messages are dropped
