> Currently the canary tool only sniff the read operations, it's hard to
> finding the problem in write path.
> To support the write sniffing, we create a system table named '_canary_' in
> the canary tool. And the tool will make sure that the region number is large
> than the number of the regionserver and the regions will be distributed onto
> all regionservers.
> Periodically, the tool will put data to these regions to calculate the write
> availability of HBase and send alerts if needed.
