Description

This JIRA is to implement a standalone program that can be used to do "canary monitoring" of a running HBase cluster. This program would gather a list of the regions in the cluster, then iterate over them doing lightweight operations (eg short scans) to provide metrics about latency as well as alert on availability issues.
