Amazon has introduced a new tagging feature for Elastic MapReduce: stakes and opportunities.

If unfamiliar, Connectikpeople recalls that Amazon Elastic MapReduce helps you process vast amounts of data using Hadoop, an open source parallel processing framework. New enhancements captured by Connectikpeople include a new tagging feature for Elastic MapReduce. This

means, henceforth you can:

·        add up to 10 tags per cluster at launch time,

·         add, remove, and edit tags while the cluster is running.

Finally, Connectikpeople recalls that, any changes that you make to the tags on the cluster will be mirrored to the EC2 instances in the cluster. In addition you can set and edit the tags from the Elastic MapReduce Console, the Elastic MapReduce Command Line, or from the Elastic MapReduce APIs.
