Matteo Bertozzi updated HBASE-4393:
-----------------------------------
Attachment: Canary-v0.java
I've attached a new version of the canary following the stack comments.
Now the canary is a tool, and has a command line with a couple of options.
In this implementations the canary runs "forever" and has a pluggable sink
interface to collect and output failures and read latencies.
At the moment the only sink implemented is the FileSink that allows to use a
file or stdout as output device. But we can add support for the hadoop metrics
later.

> 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.
