-------------------------------------
Summary: Fix for false reports of ledger unreplication during
rolling restarts.
Key: BOOKKEEPER-745
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-745
Project: Bookkeeper
Issue Type: Bug
Components: bookkeeper-auto-recovery
Reporter: Ivan Kelly
Assignee: Ivan Kelly
Fix For: 4.3.0, 4.2.3
The bug occurred because there was no check if rereplication was enabled or not
when the auditor came online. When the auditor comes online it does a check of
which bookies are up and marks the ledgers on missing bookies as
underreplicated. In the false report case, the auditor was running after each
bookie was bounced due to the way leader election for the auditor works. And
since one bookie was down since you're bouncing the server, all ledgers on that
bookie will get marked as underreplicated.
