Hi, I'm seeing an issue with the load speed of Flink Web UI when running in YARN session. Initial load takes several minutes or even more, although according to the browser console there are only a couple of MBs to download. When the loading is complete, the UI itself is quite responsive.
I don't see such an issue with YARN UI loading from the same cluster over the same network. I suspected that YARN proxy may cause the slowdown and hit the direct Flink web UI URL - the same story. CPU, load average and memory consumption on the node hosting job manager are low. I gave jobmanager from 4Gb to 10Gb heap - no effect. Any ideas on how to approach the problem are appreciated. Thanks, Yury
