Eric Badger created YARN-6988: --------------------------------- Summary: container-executor fails for docker when command length > 4096 B Key: YARN-6988 URL: https://issues.apache.org/jira/browse/YARN-6988 Project: Hadoop YARN Issue Type: Sub-task Reporter: Eric Badger Assignee: Eric Badger
{{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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
