Local cache for limited period of time would optimize > number of calls for GetFileStatus operation. > One of the example where local limited period cache would be useful - > terasort ListStatus on input directory follows with GetFileStatus operation > on each file within directory. For 2048 input files in a directory would save > 2048 GetFileStatus calls during start up (Using the ListStatus response to > cache FileStatus instances). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
