             Summary: [TESTS][SQL] TPCHQuerySuite customer.c_nationkey should be bigint instead of string
                 Key: SPARK-25439
                 URL: https://issues.apache.org/jira/browse/SPARK-25439
             Project: Spark
          Issue Type: Improvement
          Components: Tests
    Affects Versions: 2.3.1
            Reporter: Nicolas Poggi


 

The [TPCHQuerySuite|https://github.com/apache/spark/blob/be454a7cef1cb5c76fb22589fc3a55c1bf519cf4/sql/core/src/test/scala/org/apache/spark/sql/TPCHQuerySuite.scala#L72] currently has {{string}} for the {{customer.c_nationkey}} column, while it should be bigint according to [the spec|http://www.tpc.org/TPC_Documents_Current_Versions/pdf/tpc-h_v2.17.3.pdf] (identifier type). 

Note: this update would make previousTPCH results not comparable for queries using the {{customer}} table
