However, the IndexCache was only 15% full (1.5MB used on a 10MB > configured cache size). In particular was noted that the booking variable > totalMemoryUsed, was out of sync with the contents of the cache showing 96% > full, thereby drastically reducing the effectiveness of the cache. -- 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
