After importing the data.csv file and running the **STEP 1: Create a new index(ecommerce\_data) with the following mapping.**, I am getting an error: { "error": { "root\_cause": [ { "type": "resource\_already\_exists\_exception", "reason": "index [ecommerce\_data/if7D34vxR2W6IfuPPGyuKw] already exists", "index\_uuid": "if7D34vxR2W6IfuPPGyuKw", "index": "ecommerce\_data" } ], "type": "resource\_already\_exists\_exception", "reason": "index [ecommerce\_data/if7D34vxR2W6IfuPPGyuKw] already exists", "index\_uuid": "if7D34vxR2W6IfuPPGyuKw", "index": "ecommerce\_data" }, "status": 400 } Reference: [GitHub - LisaHJung/Part-4-Running-Aggregations-with-Elasticsearch-and-Kibana](https://github.com/LisaHJung/Part-4-Running-Aggregations-with-Elasticsearch-and-Kibana) ---

Please ignore this. When i imported the data, I named the index as " **ecommerce\_data**" and hence I got the error message "resource\_already\_exists\_exception" Worth suggesting in Git repo to import the file and use a name for the index as "ecommerce\_orig" Then, data cleanup would work seamlessly. ---
