---------------------------------
Summary: Leader should not evict a follower when the follower is
in the process of starting up a tablet
Key: KUDU-1407
URL: https://issues.apache.org/jira/browse/KUDU-1407
Project: Kudu
Issue Type: Bug
Components: consensus
Affects Versions: 0.8.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
It seems like, if the leader gets an error from one of its followers because
the tablet is not running, it considers this replica to be 'unresponsive'. If
this happens for 5 minutes, it will evict that follower to try to create a new
replica.
This can cause problems at cluster startup time when there is a lot of data and
a cold disk cache - the startup bootstrap process might be more than five
minutes and leaders might end up evicting followers that are perfectly healthy
(just in the process of coming up).
