> Import Process: Transforms: Handling Custom Attributes Does Not Update
> ----------------------------------------------------------------------
>
> Key: ATLAS-2906
> URL: https://issues.apache.org/jira/browse/ATLAS-2906
> Project: Atlas
> Issue Type: Bug
> Reporter: Ashutosh Mestry
> Assignee: Ashutosh Mestry
> Priority: Major
> Attachments:
> ATLAS-2906-Allow-transforms-to-be-applied-when-entit.patch
>
>
> *Background*
> The new transform framework looks at the entity holistically and computes
> attributes as it sees fit.
> Updating the _hive_storagedesc.location_ if entity-level transform is
> present, does not apply the transform.
> *Steps* *to Duplicate*
> * Attempt to import a zip file with the following transform.
> {code:java}
> { "options": { "transformers": "[{\"conditions\":{\"__entity\":\"topLevel:
> \"},\"action\":{\"__entity\":\"ADD_CLASSIFICATION:
> mycluster0_replicated\"}},{\"action\":{\"__entity.replicatedTo\":\"CLEAR:\",\"__entity.replicatedFrom\":\"CLEAR:\"}},{\"conditions\":{\"hive_db.clusterName\":\"EQUALS:
> mycluster0\"},\"action\":{\"hive_db.clusterName\":\"SET:
> mycluster1\"}},{\"conditions\":{\"hive_storagedesc.location\":\"STARTS_WITH_IGNORE_CASE:
>
> hdfs://localhost.localdomain\"},\"action\":{\"hive_storagedesc.location\":\"REPLACE_PREFIX:
> = :hdfs://localhost.localdomain=hdfs://mycluster1\"}}]", "replicatedFrom":
> "SFO$clx" } }
> {code}
> Locate any entity of type _hive_storagedesc_ and note the _location._ It does
> not apply the updated location.
> *Root Cause*
> * The new transform framework re-computes the location based on cached data.
> * Solution: Prevent caching of this attribute so that it honors the
> externally set transformation.
