Re: java.rmi.server.ExportException: Port already in use

Hi Jake, Thanks for the reply. It appears that my task fails too many times within the yarn.container.retry.window.ms ​ window. Increasing yarn.container.retry.count​seems to solve the issue for the time being. It still remains unknown why my tasks are failing so often. There is no error messages

Location of the RocksDB Key-Value store
