      Description

      In GraphFrames, test test("named edges") in PatternMatchSuite surfaces a SQL codegen bug.
      This is described in https://github.com/graphframes/graphframes/issues/165

      Summary

      • The unit test does a simple motif query on a graph. Essentially, this means taking 2 DataFrames, doing a few joins, selecting 2 columns, and collecting the (tiny) DataFrame.
      • The test runs, but codegen fails. See the linked GraphFrames issue for the stacktrace.

      To reproduce this:

      Copying Felix Cheung's comment from the GraphFrames issue 165:

      Seems like codegen bug; it looks like at least 2 issues:
      1. At L472, inputadapter_value is not defined within scope
      2. inputadapter_value is an InternalRow, for this statement to work
      bhj_primitiveA = inputadapter_value;
      it should be
      bhj_primitiveA = inputadapter_value.getLong(0);
