> Now the scanner id is a long number from 1 to max in a region server. Each new scanner
will have a scanner id.
> If a client has a scanner whose id is x, when the RS restart and the scanner id is also
incremented to x or a little larger, there will be a scanner id collision.
> So the scanner id should now be same during each time the RS restart. We can add the
start timestamp as the highest several bits in scanner id uint64.
> And because HBASE-18121 is not easy to fix and there are many clients with old version.
We can also encode server host:port into the scanner id.
> So we can use ServerName.
