> Key: ATLAS-3315
> URL: https://issues.apache.org/jira/browse/ATLAS-3315
> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 1.2.0, 2.0.0
> Reporter: Ashutosh Mestry
> Assignee: Ashutosh Mestry
> Priority: Major
> Fix For: 1.2.0, 2.0.0, trunk
>
> Attachments: AltasJanusGraph-Init-exception-fix.patch
>
>
> *Description*
> Case where _JanusGraphFactory.open_ throws an exception, the initialization goes into an infinite loop.
> _Expected Behavior_: The exception should be logged and initialization should exit.
> _Actual Behavior_: Initialization goes into an infinite loop.
> _Root cause:_
> # If _JanusGraphFactory.open_ encounters errors, we log it and proceed with construction of _AtlasJanusGraphDatabase_.
> # The ctor of _AtlasJanusGraphDatabase_ calls _getInstance_ which goes back to step 1.
> *Solution*
> Handle exception and log, initialize _AtlasJanusGraphDatabase_ only on successful completion of _JanusGraphFactory.open._
