Try this: set mapred.map.tasks=28; Zheng From: Ryan LeCompte [mailto:[email protected]] Sent: Thursday, December 10, 2009 1:45 PM To: [email protected] Subject: Hive not using the full mapper capacity for certain jobs
Hello all, The cluster has a capacity of 28 concurrent mappers. It looks like on larger tables Hive will use all 28 mappers, but on a smaller table it only uses 4 mappers maximum. Any idea how to override this? Thanks, Ryan
