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.
