Hadoop and Apache HBase Configurations - Comparing the Use of Amazon DynamoDB and Apache HBase for NoSQL

Hadoop and Apache HBase Configurations

You can use a bootstrap action to install additional software or change Apache HBase or Apache Hadoop configuration settings on Amazon EMR. Bootstrap actions are scripts that are run on the cluster nodes when Amazon EMR launches the cluster. The scripts run before Hadoop starts and before the node begins processing data.

You can write custom bootstrap actions or use predefined bootstrap actions provided by Amazon EMR. For example, you can install Ganglia to monitor Apache HBase performance metrics using a predefined bootstrap action on Amazon EMR.
