>             Project: Atlas
>          Issue Type: Bug
>          Components: atlas-intg
>    Affects Versions: trunk
>            Reporter: Ashutosh Mestry
>            Assignee: Ashutosh Mestry
>            Priority: Major
>             Fix For: trunk
>         Attachments: ATLAS-3796-Status-Reporter-processed-set-cleanup.patch
> *Background*
> _Migration Import_ implementation introduced _StatusReporter_. The class maintains GUIDs
of entities that are to be processed and entities that are processed. When the entity is marked
as processed, it needs to be removed from the processed set.
> *Steps to Duplicate*
> _Pre-requisites_
> Large migration import dataset (over 50 M entities).
> _Steps to Duplicate_
>  * Start importing the dataset.
>  * After over 60%, the Atlas server will crash with out of memory exception.
> _Expected results_: Migration Import should continue without problems.
> _Actual results_: Atlas server crashes with out of memory exception, hprof dump indicates
large number of items allocated by _StatusReporter.processedSet_.
> _Additional information_: This bug does not affect status reporting.
> _Work around_: Resume migration import. It will continue without problems.
