Review request for atlas, Jayendra Parab, Mandar Ambawane, Pinal Shah, and 
Sheetal Shah.


Bugs: ATLAS-4856
    https://issues.apache.org/jira/browse/ATLAS-4856


Repository: atlas


Description
-------

Problem Statement:
This is an intermittent issue the possibilities of reproducing this issue are:

1. When 2 parallel imports running which has some overlapping entities.
2. If more than 10 parallel imports are running which has no overlapping 
entities.
3. Performing parallel imports on fresh atlas server which has no entities 
present.

Fix:
As permanent failures can be caused by complete connection loss, hardware 
failure or lock contention. So, found one of the solution to fix this 
exception, is by retrying the transaction.
