Summary: codegen bug surfaced by GraphFrames issue 165
Key: SPARK-20111
URL: https://issues.apache.org/jira/browse/SPARK-20111
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.1.0, 2.0.2, 2.2.0
Reporter: Joseph K. Bradley
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:
* Check out GraphFrames https://github.com/graphframes/graphframes
* Run {{sbt assembly}} to compile it and run tests
