---------------------------------
Assignee: Shwetha G S
> Atlas is sending an ENTITY_CREATE event to the ATLAS_ENTITIES topic even if
> the entity exists already.

> Key: ATLAS-342

> Project: Atlas
> Issue Type: Bug
> Reporter: Hemanth Yamijala
> Assignee: Shwetha G S
>
> * Configure Hive hook in Hive.
> * Configure Atlas to talk to Kafka topics on a separately set Kafka instance.
> * Run a script to create tables in Hive multiple times, for e.g.
> {code}
> for i in `seq 1 10`; do ./bin/hive -e "create table tbl$i (column${i}1
> string, column${i}2 int)"; done
> {code}
> * After the script completes, check the number of entities & list the actual
> entities in the ATLAS_ENTITIES topic.
> We can see one ENTITY_CREATE event for the Hive database for every table
> created in Hive. For e.g.:
> {code}
> {"entity":{"jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference","id":{"jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Id","id":"e7ed4ad9-1fba-47ad-a089-1ff7e715c1ad","version":0,"typeName":"hive_db"},"typeName":"hive_db","values":{"name":"default","description":"Default
> Hive
> database","ownerType":{"value":"ROLE","ordinal":2},"qualifiedName":"primary.default","locationUri":"hdfs://localhost:9000/user/hive/warehouse","ownerName":"public","clusterName":"primary"},"traitNames":[],"traits":{}},"operationType":"ENTITY_CREATE","traits":[]}
> {"entity":{"jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference","id":{"jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Id","id":"e7ed4ad9-1fba-47ad-a089-1ff7e715c1ad","version":0,"typeName":"hive_db"},"typeName":"hive_db","values":{"name":"default","description":"Default

> {code}
> The expectation is that we don't have these extraneous events as there is no
> change to the entity.
