Guanghao Zhang commented on HBASE-15615:
----------------------------------------
When set HConstants.HBASE_CLIENT_RETRIES_NUMBER to 0, AsyncProcess will have
the same retry behavior with 1. But if HConnection's numRetries set to 0, it
can't locate region.
{code}
if (tries >= localNumRetries) {
throw new NoServerForRegionException("Unable to find region for "
+ Bytes.toStringBinary(row) + " in " + tableName +
" after " + localNumRetries + " tries.");
}
{code}
bq. in HBaseTestingUtility we use new RetryCounter(numRetries+1, (int)pause,
TimeUnit.MICROSECONDS);
I am not sure if this make other ut fail.
Maybe we should open a new issue to fix HBASE_CLIENT_RETRIES_NUMBER?

> In RpcRetryingCallerImpl, it get pause time by expectedSleep =
> callable.sleep(pause, tries + 1); And in RegionServerCallable, it get pasue
> time by sleep = ConnectionUtils.getPauseTime(pause, tries + 1). So tries will
> be bumped up twice. And the pasue time is 3 * hbase.client.pause when tries
> is 0.
> RETRY_BACKOFF = {1, 2, 3, 5, 10, 20, 40, 100, 100, 100, 100, 200, 200}
