------------------------------------------
Summary: 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: Bug
Components: Sentry
Affects Versions: sentry-ha-redesign
Reporter: Alexander Kolbasov
Priority: Minor
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.
