Xiaolin Ha updated HBASE-27676:
-------------------------------
Description:
{code:java}
int scanQueues = Math.max(0, (int) Math.floor(readQueues * callqScanShare));
int scanHandlers = Math.max(0, (int) Math.floor(readHandlers * callqScanShare));
if ((readQueues - scanQueues) > 0) {
readQueues -= scanQueues;
readHandlers -= scanHandlers;
} else {
scanQueues = 0;
scanHandlers = 0;
} {code}
When readQueues * callqScanShare < 1 but readHandlers * callqScanShare > 1,
there will be some iddle scan handlers with NO scan queues.

} else {
scanQueues = 0;
scanHandlers = 0;
} {code}
When readQueues * callqScanShare < 1 but readHandlers * callqScanShare > 1,
there will be some active scan handlers with NO scan queues.
> Scan handlers in the RPC executor should match at least one scan queues
