Hudson commented on BOOKKEEPER-946: ----------------------------------- FAILURE: Integrated in Jenkins build bookkeeper-master #1599 (See [https://builds.apache.org/job/bookkeeper-master/1599/]) BOOKKEEPER-946: Provide an option to delay auto recovery of lost bookies (sijie: rev 669ab4ac32bcbf6b3d883a07ed942d36d25b8a6e) * (edit) bookkeeper-server/src/test/java/org/apache/bookkeeper/replication/AuditorLedgerCheckerTest.java > Provide an option to delay auto recovery of lost bookies > -------------------------------------------------------- > > Key: BOOKKEEPER-946 > URL: https://issues.apache.org/jira/browse/BOOKKEEPER-946 > Project: Bookkeeper > Issue Type: Improvement > Components: bookkeeper-server > Affects Versions: 4.5.0 > Reporter: Rithin Shetty > Assignee: Rithin Shetty > Fix For: 4.5.0 > > Attachments: > org.apache.bookkeeper.replication.AuditorLedgerCheckerTest-output.txt, > org.apache.bookkeeper.replication.AuditorLedgerCheckerTest-output.txt > > > If auto recovery is enabled, and a bookie goes down for upgrade or even if it > looses zk connection intermittently, the auditor detects it as a lost bookie > and starts under replication detection and the replication workers on other > bookie nodes start replicating the under replicated ledgers. All of this > stops once the bookie comes up but by then a few ledgers would get > replicated. Given the fact that we have multiple copies of data, it is > probably not necessary to start the recovery as soon as a bookie goes down. > We can probably wait for an hour or so and then start recovery. This should > cover cases like planned upgrade, intermittent network connectivity loss, > etc. The amount of time to wait can be an option and the default would be to > not wait at all(i.e. retain current behavior). > Of course, if more than one bookie goes down within a short interval, we > could decide to start auto recovery without waiting. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
