Review request for atlas, Jayendra Parab, Nikhil Bonte, and Sarath Subramanian.
Bugs: ATLAS-4285
https://issues.apache.org/jira/browse/ATLAS-4285
Repository: atlas
Description
-------
**Steps to Duplicate**
_Setup_:
- Create a linear lineage using chained CTAS queries via Hive or REST APIs E.g.
```
create view abcd_vw_1 as select * from abc;
create view abcd_vw_2 as select * from abcd_vw_1;
create view abcd_vw_3 as select * from abcd_vw_2;
.
.
.
```
This should result in a long lineage.
- Create 3 classifications, say C1, C2, C3.
- Assign C1 to abcd_vw_1, C2 to abcd_vw_2 and C3 to abcd_vw_3.
Expected result: abcd_vw_n should have all the 3 classifications propagated.
**Aproach**
Modify _propagateClassification_ to lock all the impacted vertices. Requests
attempting to modify the same entity will thus be blocked.
