Andrew Martin commented on BEAM-741: ------------------------------------ I found this issue when using the Direct Runner for a test, which does dynamic re-sharding as part of the Write transform. It does a GroupByKey -> Values -> Flatten, and Flatten failed because it did not have an 'IterableLikeCoder' as the input coder, which should be the case after calling Values form a GBK. > Values transform does not use the correct output coder when values is an > Iterable<T> > ------------------------------------------------------------------------------------ > > Key: BEAM-741 > URL: https://issues.apache.org/jira/browse/BEAM-741 > Project: Beam > Issue Type: Bug > Components: sdk-java-core > Reporter: Andrew Martin > Assignee: Davor Bonaci > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
