Я столкнулся с проблемой, что "Невозможно предоставить кодировщик для org.apache.hadoop.hbase.client.Mutation." используя HbaseIO с FlinkRunner.
Исключение ниже:
Exception in thread "main" java.lang.IllegalStateException: Unable to return a default Coder for ParDo(HBaseProfile)/ParMultiDo(HBaseProfile).output [PCollection]. Correct one of the following root causes:
No Coder has been manually specified; you may do so using .setCoder().
Inferring a Coder from the CoderRegistry failed: Unable to provide a Coder for org.apache.hadoop.hbase.client.Mutation.
Building a Coder using a registered CoderProvider failed.
See suppressed exceptions for detailed failures.
Using the default output Coder from the producing PTransform failed: PTransform.getOutputCoder called.
