wangyang0918 commented on issue #10193: [FLINK-13938][yarn] Use pre-uploaded flink binary to accelerate flink submission URL: https://github.com/apache/flink/pull/10193#issuecomment-558013369 @walterddr Your assumption 1 is right. For assumption 2, the pre-uploaded flink binary is located on a generic location of any kind of DFS system(usually HDFS), not Yarn distributed cache. We register the pre-uploaded flink jars as Yarn public cache, so that it could be shared by different applications. And they will not be downloaded every time. For #10187, @TisonKun will create a separate JIRA. It is focused on support shipping directory located on HDFS.
