Testing
-------
**Unit tests**
None.
**Functional tests**
Used the script below to concurrently create same entity. See attached (t.json)
that contains entity payload.
Steps to test:
1. Deploy Atlas without this patch (or any other patch) with *setConsistency*.
2. Execute the script below with the payload *t1.json*.
3. Notice that multiple entities of *hdfs_path* type get created. Few of the
REST calls may fail with *AtlasSchemaViolation* exception.
4. Deploy this change and restart Atlas. Notice that the new patch gets applied.
5. Modify *t1.json* by replacing e1 with e2.
6. Execute the script below.
7. Notice that only 1 entity *hdfs_path* with name e2 gets created.
*multiple-curl.sh*
```bash
#!/bin/bash
URL=<server>
echo ${URL}
for i in `seq 10`; do
curl -u admin:admin123 -X POST http://${URL}:31000/api/atlas/v2/entity/bulk
--header 'Content-Type: application/json' -d @./t.json &
done
```
