How to perfrom update (REST API - PUT) operation of apache atlas entity

IHi All,

I am getting one issue while updating my existing entity using PUT calls.

I have downloaded json by using GET and i just trying to update my entity (i have tried updating description also tried not updating anything and PUT as it is ) using PUT operation and its failing with same reason  -  

"errorCode":"ATLAS-400-00-023","errorMessage":"Attribute null not found for type hive_table"   

could you please advise how did you update the entity using PUT command ?   

curl --negotiate -u : -X PUT   -H "Content-Type: application/json"   https://myURL:portNumber/api/atlas/v2/entity/guid/<myGuid>-d @downloaded_entity.json

 

i have referred this post , however its not showing how to perform PUT operation.   Solved: Re: PARTIAL UPDATE APACHE ATLAS ENTITY GUI - Cloudera Community - 297845

 

so my question is - Does atals REST PAI allows updating entity ?  my usecase is i want to update an hive table entity. I have hive table hive column relationship in place. now i want to update my hive-table entity by adding hive columns under attributes: { columns [...]}

    @bigdatacm Can you try this I hope it will work

    i.e

    curl " https://URL/api/atlas/v2/entity/guid/7g5678h9-4003-407a-ac00-791c7c53e6d5" \
    -i -X GET --negotiate \
    -H 'Content-Type: application/json' \
    -H 'Accept: application/json' \
    -u username:password >> test_oracle_tbl.json -k

    and then modify the test_oracle_tbl.json and make a partial update to the entity

    curl "https://hostname:port/api/atlas/v2/entity/uniqueAttribute/type/datsetname?attr:qualifiedName=name"
    -i -X GET --negotiate \
    -H 'Content-Type: application/json' \
    -H 'Accept: application/json' \
    -u username:password -d@test_oracle_tbl.json -k

    Hello,  yes Atlas API allows updating the entity https://atlas.apache.org/api/v2/resource_EntityREST.html

    Further as per the error shared, looks like some missing attributes in the updated JSON that you are trying to push, verify it once or if possible attach it here for a quick review.

        I'm facing an issue while performing a PUT operation to update an Apache Atlas entity. I'm getting the error: "errorCode":"ATLAS-400-00-023","errorMessage":"Attribute null not found for type hive_table", despite trying different update approaches. Could someone advise on how to correctly update an entity using the PUT command, or confirm if Atlas REST API supports entity updates?

          @jhoney12  yes Atlas Rest API supports , but you need to download the JSON for the entity first.

          i.e

          curl " https://URL/api/atlas/v2/entity/guid/7g5678h9-4003-407a-ac00-791c7c53e6d5" \
                  -i -X GET --negotiate \
                  -H 'Content-Type: application/json' \
                  -H 'Accept: application/json' \
                  -u username:password >> test_oracle_tbl.json -k

          and then modify the test_oracle_tbl.json and make a partial update to the entity

          curl "https://hostname:port/api/atlas/v2/entity/uniqueAttribute/type/datsetname?attr:qualifiedName=name"
          -i -X GET --negotiate \
                  -H 'Content-Type: application/json' \
                  -H 'Accept: application/json' \
                  -u username:password -d@test_oracle_tbl.json -k
