Brachi Packter created BEAM-8109:
------------------------------------
Summary: Encoder exception for structure contains Iterable of KV
Key: BEAM-8109
URL: https://issues.apache.org/jira/browse/BEAM-8109
Project: Beam
Issue Type: Bug
Components: extensions-java-sorter
Affects Versions: 2.15.0, 2.14.0
Reporter: Brachi Packter
When doing group by and then sort, the sort should get this structure:
PCollection<KV<PrimaryKeyT, Iterable<KV<SecondaryKeyT, ValueT>>>>
However, for any SecondaryKeyT that I put I get coder exception:EOF, this
happens for long and for string coders.
Happens in DataFlow runner.
Here is the full exception:
