Reid Chan created HBASE-22559:
---------------------------------
Summary: [RPC] set guard against CALL_QUEUE_HANDLER_FACTOR_CONF_KEY
Key: HBASE-22559
URL: https://issues.apache.org/jira/browse/HBASE-22559
Project: HBase
Issue Type: Bug
Components: rpc
Reporter: Reid Chan
Assignee: Reid Chan
CALL_QUEUE_HANDLER_FACTOR_CONF_KEY is
{{hbase.ipc.server.callqueue.handler.factor}}, a float number, which is
supposed between [0.0, 1.0].
If it is greater than 1, for example, 2.0, the call queues and handlers will be
expanded twice:
{code}
float callQueuesHandlersFactor =
this.conf.getFloat(CALL_QUEUE_HANDLER_FACTOR_CONF_KEY, 0);
this.numCallQueues = computeNumCallQueues(handlerCount,
callQueuesHandlersFactor);
this.handlerCount = Math.max(handlerCount, this.numCallQueues);
protected int computeNumCallQueues(final int handlerCount, final float
callQueuesHandlersFactor) {
return Math.max(1, (int) Math.round(handlerCount * callQueuesHandlersFactor));
}
{code}
We already have {{hbase.regionserver.handler.count}} set, what mentioned above
looks tricky.
