roshannaik edited a comment on issue #10089: [FLINK-12342][yarn] Remove container requests in order to reduce excess containers URL: https://github.com/apache/flink/pull/10089#issuecomment-566354943 Was directed to this patch by @HuangZhenQiu. Applied this to Flink 1.6 and used it to launch a job with 500 yarn containers. See definite improvement with the overallocation problem. However once the job comes up (as per yarn ui), the Flink UI for the job fails to load. Perhaps the UI is having trouble with large number of containers ? Have there been any scalability improvements to the UI that we can additionally also try out ?
