---------------------------------------
Summary: HBaseIO.Read not deterministic coder exception when
executed with flink 1.10.1
Key: BEAM-10375
URL: https://issues.apache.org/jira/browse/BEAM-10375
Project: Beam
Issue Type: Bug
Components: io-java-hbase
Affects Versions: 2.21.0
Reporter: Richard Moorhead
Given that HBaseIO.readAll() is applied to a PCollection<HBaseIO.Read>, the
following exception is thrown when readAll is executed by the flink runner:
{code:java}
The program finished with the following exception:
org.apache.flink.client.program.ProgramInvocationException: The main method
caused an error: the keyCoder of a GroupByKey must be deterministic
