Eric Badger updated YARN-6988:
------------------------------
Attachment: YARN-6988.001.patch
Attaching a patch to increase the size of the docker commands to 128 KB. This
would decouple it from EXECUTOR_PATH_MAX and not override the change that
[~vvasudev] is making in YARN-6623.
> container-executor fails for docker when command length > 4096 B

>
> {{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.
