org.apache.nifi.atlas.provenance.AbstractNiFiProvenanceEventAnalyzer

org.apache.nifi.atlas.provenance.analyzer.AbstractHiveAnalyzer

org.apache.nifi.atlas.provenance.analyzer.Hive2JDBC

All Implemented Interfaces:

NiFiProvenanceEventAnalyzer

public class Hive2JDBC
extends AbstractHiveAnalyzer

Analyze provenance events for Hive2 using JDBC.

• If a Provenance event has 'query.input.tables' or 'query.output.tables' attributes then 'hive_table' DataSet reference is created:
  • qualifiedName=tableName@namespace (example: myTable@ns1)
  • name=tableName (example: myTable)
• If not, 'hive_database' DataSet reference is created from transit URI:
  • qualifiedName=dbName@namespace (example: default@ns1)
  • dbName (example: default)
