This can cause issues with YARN localization > that destabilize the cluster and potentially impact other user jobs. These > resources are specified via the files, libjars, archives and jobjar command > line arguments or directly through the configuration (i.e. distributed cache > api). The resources specified could be too large in multiple dimensions: > # Total size > # Number of files > # Size of an individual resource (i.e. a large fat jar) > We would like to encourage good behavior on the client side by having the > option of enforcing resource limits along the above dimensions. > There should be a separate effort to enforce limits at the YARN layer on the > server side, but this jira is only covering the map reduce layer on the > client side. In practice, having these client side limits will get us a long > way towards preventing these localization anti-patterns. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
