> Like Hadoop or Spark, etc. Flink should support configuration via shell environment variables. In cluster setups, this makes things a lot easier because writing config files can be omitted. Many automation tools (e.g. Google's bdutil) use (or abuse) this feature.
> For example, to set up the task manager heap size, we would run `export FLINK_TASKMANAGER_HEAP=4096` before starting the task manager on a node to set the heap memory size to 4096MB.
> Environment variables should overwrite the regular config entries.
