Subject number of map tasks on yarn
Date Wed, 02 Apr 2014 01:08:31 GMT
Hi all,

I pretty much use the default yarn setting to run a word count example on
a 3 node cluster. Here are my settings:
yarn.nodemanager.resource.memory-mb 8192
yarn.scheduler.minimum-allocation-mb 1024
yarn.scheduler.maximum-allocation-vcores 32

I would expect to see 8192/1024 * 3 = 24 map tasks.
However, I see 32 map tasks. Anybody knows why? Thanks.

Libo
