-- `containerized.heap-cutoff-ratio`: (Default 0.25) Percentage of heap
space to remove from containers started by YARN. When a user requests a certain
amount of memory for each TaskManager container (for example 4 GB), we can not
pass this amount as the maximum heap space for the JVM (`-Xmx` argument)
because the JVM is also allocating memory outside the heap. YARN is very strict
with killing containers which are using more memory than requested. Therefore,
we remove this fraction of the memory from the requested heap as a safety
margin and add it to the memory used off-heap.
-- `containerized.heap-cutoff-min`: (Default 600 MB) Minimum amount of
memory to cut off the requested heap size.
-- `yarn.maximum-failed-containers` (Default: number of requested
containers). Maximum number of containers the system is going to reallocate in
case of a failure.
-- `yarn.application-attempts` (Default: 1). Number of ApplicationMaster
restarts. Note that that the entire Flink cluster will restart and the YARN
Client will loose the connection. Also, the JobManager address will change and
you'll need to set the JM host:port manually. It is recommended to leave this
option at 1.
-- `yarn.heartbeat-delay` (Default: 5 seconds). Time between heartbeats
with the ResourceManager.
-- `yarn.properties-file.location` (Default: temp directory). When a Flink
job is submitted to YARN, the JobManager's host and the number of available
processing slots is written into a properties file, so that the Flink client is
able to pick those details up. This configuration parameter allows changing the
default location of that file (for example for environments sharing a Flink
installation between users)
-- `yarn.containers.vcores` The number of virtual cores (vcores) per YARN
container. By default, the number of `vcores` is set to the number of slots per
TaskManager, if set, or to 1, otherwise.
-- `containerized.master.env.`*ENV_VAR1=value* Configuration values
prefixed with `containerized.master.env.` will be passed as environment
variables to the ApplicationMaster/JobManager process. For example for passing
`LD_LIBRARY_PATH` as an env variable to the ApplicationMaster, set:
- `containerized.master.env.LD_LIBRARY_PATH: "/usr/lib/native"`
-- `containerized.taskmanager.env.` Similar to the configuration prefix
about, this prefix allows setting custom environment variables for the
-- `yarn.container-start-command-template`: Flink uses the following
template when starting on YARN:

I see this in the doc and it's referenced twice in comments in tests but
you can't actually set this anymore, can you?
