dawidwys opened a new pull request #7520: [FLINK-11293][kafka, test] Added timeout to delete topic request.
URL: https://github.com/apache/flink/pull/7520
 
 
   
   
   ## What is the purpose of the change
   
   The purpose of this PR is to harden kafka ITCases. It targets probable kafka AdminClient connection issues.
   
   ## Brief change log
   
   Logs from failures show that even though the request never finishes,
   kafka topics are actually deleted. Therefore this PR adds timeout on
   delete request. If the request times out we check if the topic actually
   exists. If not then we continue as if the delete request succeeded.
   
   ## Verifying this change
   
   Current kafka ITCases still pass.
