Alexander Kolbasov resolved SENTRY-1440. ---------------------------------------- Resolution: Won't Fix Assignee: Alexander Kolbasov Fix Version/s: sentry-ha-redesign We are no longer using fencing > Fencing implementation in sentry-ha can create two fencing tables > ----------------------------------------------------------------- > > Key: SENTRY-1440 > URL: https://issues.apache.org/jira/browse/SENTRY-1440 > Project: Sentry > Issue Type: Sub-task > Components: Sentry > Affects Versions: sentry-ha-redesign > Reporter: Alexander Kolbasov > Assignee: Alexander Kolbasov > Priority: Minor > Fix For: sentry-ha-redesign > > > The fencing code in sentry-ha has a logic that creates a fencing table when > it doesn't exist. The problem is that this code isn't atomic. It is possible > for two processes to create their fencing table at the same time. This is > rather bad because the remaining fencing code checks that only one such table > exists and fails otherwise. > Note that for this to happen the fencing table shouldn't exist and both > processes should decide to become active, so this isn't something that is > likely to happen, but it is still good to fix. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
