Guanghao Zhang commented on HBASE-15615:
----------------------------------------
When working with this issue, I found that hbase.client.retries.number has
different meanings in branch-1 and master. In branch-1, the max attempts number
equals with hbase.client.retries.number. But in master, the max attempts number
equals with hbase.client.retries.number + 1. I am not sure which one is right.
The comment of hbase.client.retries.number is:
{code}
/**
* Parameter name for maximum retries, used as maximum for all retryable
* operations such as fetching of the root region from root region server,
* getting a cell's value, starting a row update, etc.
*/
public static final String HBASE_CLIENT_RETRIES_NUMBER =
"hbase.client.retries.number";
{code}
> Wrong sleep time when RegionServerCallable need retry

> 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}
