> 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.
