Review request for atlas, Jayendra Parab, Mandar Ambawane, Pinal Shah, and
Sheetal Shah.
Bugs: ATLAS-4847
https://issues.apache.org/jira/browse/ATLAS-4847
Repository: atlas
Description
-------
Steps to reproduce:
1. Create a hive_table entity and assign a term to it.
2. Perform 1st incremental export of that entity without using changeMarker.
3. Without any modification on that entity perform 2nd consecutive incremental
export with changeMarker from previous export.
Result is it that it throws NullPointerException and export is failed.
Problem:
When an entity which has termed assigned was exported with changeMarker value
greater than value of lastModified time of that entity it resulted in throwing
NullPointerException.
Solution:
1. NullPointerException occured because it was trying to fetch referred
entities of AtlasGlossary Object while performing export operation and as
AtlasGlossary didn't have any referred entities it gave raise this exception.
2. This problem is solved by handling NullPointer before trying to fetch
referred entities.
