     [ https://issues.apache.org/jira/browse/FLINK-20620?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

godfrey he updated FLINK-20620:
-------------------------------

> Port StreamExecPythonCalc and BatchExecPythonCalc to Java
> ---------------------------------------------------------
>
>                 Key: FLINK-20620
>                 URL: https://issues.apache.org/jira/browse/FLINK-20620
>             Project: Flink
>          Issue Type: Sub-task
>          Components: Table SQL / Planner
>            Reporter: godfrey he
>            Priority: Major
>
> https://issues.apache.org/jira/browse/FLINK-20610 will separate the implementation of BatchExecCalc and StreamExecCalc, and port StreamExecCalc
> {{StreamExecPythonCalc}} extends from {{CommonExecPythonCalc}} and {{CommonExecPythonCalc}} extends from {{CommonPythonBase}}, they are all Scala classes. Java class can't extend Scala interface with default implementation. So I create an issue separately to port them to Java.
