There is other issue with running hadoop on EC2 (w/o S3). Instance storage is relatively small - about 3.6 TB on largest instance and 1.5 TB on other "large" instances. In typical Hadoop machine I would expect about 8TB. So local storage is prohibitively expensive for the big data tasks.
In the same time - if we use local storage we a loosing elasticity - we have to run cluster all the time, even there is no jobs to run. It kills main point of using hadoop in the cloud - to pay for the computational resources on demand. |
