> Backup master will never come up if primary master dies during initialization
> -----------------------------------------------------------------------------
>
> Key: HBASE-8519
> URL: https://issues.apache.org/jira/browse/HBASE-8519
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 0.94.7, 0.95.0
> Reporter: Jerry He
> Assignee: Jerry He
> Priority: Minor
> Fix For: 0.98.0
>
> Attachments: HBASE-8519-trunk.patch, HBASE-8519-trunk-v2.patch

> The problem happens if primary master dies after becoming master but before
> it completes initialization and calls clusterStatusTracker.setClusterUp(),
> The backup master will try to become the master, but will shutdown itself
> promptly because it sees 'the cluster is not up'.
> This is the backup master log:
