dianfu opened a new pull request, #26062:
URL: https://github.com/apache/flink/pull/26062

   ## What is the purpose of the change
   
   *This pull request fixes the issue that the distributed cache was cleared in 
StreamExecutionEnvironment.configure. It has side effect that distributed 
caches set before will be cleared. It may happen in the case that a job mixes 
use of the DataStream API and Java Table API and it has set distributed cache 
in the DataStream API. I encountered this issue in a PyFlink job which mixes 
use of DataStream API and Table API.*
