Andras Salamon commented on OOZIE-2755: --------------------------------------- We might just return true in this case as suggested [here|https://mail-archives.apache.org/mod_mbox/oozie-user/201612.mbox/%3CCA+ygShDPz97uygHTSXeL-sUzk8h3=DFJbGdDoj+93XbSSt6=c...@mail.gmail.com%3E] but without zookeper we will run into other problems. Maybe throwing a better exception would be better. Not only {{isJobIdForThisServer}} is affected, {{getJobIdsForThisServer}} should be also checked. > Oozie HA: ZKJobsConcurrencyService throws runtime exception when numOozies is > zero > ---------------------------------------------------------------------------------- > > Key: OOZIE-2755 > URL: https://issues.apache.org/jira/browse/OOZIE-2755 > Project: Oozie > Issue Type: Bug > Components: HA > Reporter: Dongying Jiao > Priority: Major > > Setting up Oozie HA using virtual IP, {{server-1}} and {{server-2}} > (active-active), when we take down {{server-1}} any Oozie job submitted fails > with below stacktrace.
