[jira] [Created] (ATLAS-3057) Index Repair Tool: Add JanusGraph-Specific Index Repair Tool

Ashutosh Mestry created ATLAS-3057:
--------------------------------------

             Summary: Index Repair Tool: Add JanusGraph-Specific Index Repair Tool
                 Key: ATLAS-3057
                 URL: https://issues.apache.org/jira/browse/ATLAS-3057
             Project: Atlas
          Issue Type: Bug
            Reporter: Ashutosh Mestry
            Assignee: Ashutosh Mestry


*Background*

For Atlas version that uses _HBase_ and _Solr_, occasionally if Solr is down and entities get created, then there is no record of the created entities within Solr. Basic search does not indicate presence of such entities.

*Solution*

Index Repair Tool (which was present in branch-0.8) should be implemented for JanusGraph.

*Implementation Guidance*
 * Create Java-based implementation rather than Groovy script that needs graphdb-specific shell to be installed. 
 * Use JanusGraph APIs for restore instead of custom per-vertex logic.
