Eric Badger commented on YARN-6988:
-----------------------------------
We should definitely increase the limit, but don't want to malloc the entire
max amount of memory that the system allows, since that would be a waste. A
compromise could be to set the arg length to the min of the system value and
128K.

> {{run_docker}} and {{launch_docker_container_as_user}} allocate their command
> arrays using EXECUTOR_PATH_MAX, which is hardcoded to 4096 in
> configuration.h. Because of this, the full docker command can only be 4096
> characters. If it is longer, it will be truncated and the command will fail
> with a parsing error. Because of the bind-mounting of volumes, the arguments
> to the docker command can quickly get large. For example, I passed the 4096
> limit with an 11 disk node.
