----------------------------------
Summary: UnsupportedOperationException in
LazyAggregateCombineFn.mergeAccumulators
Key: BEAM-12312
URL: https://issues.apache.org/jira/browse/BEAM-12312
Project: Beam
Issue Type: Bug
Components: dsl-sql-zetasql
Reporter: Kyle Weaver
Assignee: Kyle Weaver
Another thing that works on the direct runner but fails on Dataflow:
LazyAggregateCombineFn.mergeAccumulators [1] throws an
UnsupportedOperationException because the "remove" method is not implemented in
CombineFns$ProjectionIterable [2]. We will have to modify the implementation of
LazyAggregateCombineFn.mergeAccumulators accordingly.
