> Key: ATLAS-3776
> URL: https://issues.apache.org/jira/browse/ATLAS-3776
> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 3.0.0
> Reporter: Damian Warszawski
> Priority: Minor
> Fix For: 2.1.0, 3.0.0
>
>
> EntitySearchProcessor fails when doing search by classification and specify
> orderBy attribute. The issue is that for graph query you cannot refer to
> attribute by name but need to provide absolute path to entity attribute e.g.
>
> ```
> { "attributes": [ "description", "comment", "popularityScore" ],
> "classification": "customer_NON_PII", "excludeDeletedEntities": "False",
> "limit": "", "offset": 100, "sortBy": "Table.popularityScore", "sortOrder":
> "DESCENDING", "typeName": "hive_table" }
> ```
> this query fails with following exception:
>
> ```
> {"exception":{"message":"Provided key does not exist:
> Table.popularityScore","class":"java.lang.IllegalArgumentException","stacktrace":"java.lang.IllegalArgumentException:
> Provided key does not exist: hive_table.popularityScore\n\tat
> com.google.common.base.Preconditions.checkArgument(Preconditions.java:163)\n\tat
> org.janusgraph.graphdb.query.graph.GraphCentricQueryBuilder.
> orderBy(GraphCentricQueryBuilder.java:160)
> ```
>
> When specify full reference to attribute e.g.
>
> ```
> { "attributes": [ "description", "comment", "popularityScore" ],
> "classification": "customer_NON_PII", "excludeDeletedEntities": "False",
> "limit": "", "offset": 100, "sortBy": "Table.popularityScore", "sortOrder":
> "DESCENDING", "typeName": "hive_table" }
> ```
> it fails on validation stage
>
> ```
> {"exception":{"message":"Attribute Table.popularityScore not found for type
> Table","class":"org.apache.atlas.exception.AtlasBaseException","stacktrace":"org.apache.atlas.exception.AtlasBaseException:
> Attribute Table.popularityScore not found for type Table\n\tat
> org.apache.atlas.discovery.SearchContext.validateAttributes(SearchContext.java:288)
> ```
> workaround is provided as a patch.
