----------------------------------------
Summary: graph query fails when orderBy attribute is specified
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
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:
hive_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.
