This does lead to a > // small overcommit of resources. > executor.mutable_resources()->MergeFrom( > Resources::parse( > "cpus:" + stringify(DEFAULT_EXECUTOR_CPUS) + ";" + > "mem:" + stringify(DEFAULT_EXECUTOR_MEM.megabytes())).get()); > ... > } > {code} > This leads to an overcommit of the slave. Ideally, for command tasks we can > "transfer" all of the task resources to the executor at the slave / isolation > level. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
