If there are > millions of application files to cache, it will become a time demanding > action. > In our cluster, it'll be 4+ hours before the initialization is done. > We added a switch to control whether doing initialized cache or not. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
