> In hbase-default.xml (and also in HBase Book), the description of hbase.client.retries.number
is:
> {quote}
> Maximum retries.  Used as maximum for all retryable operations such as the getting of
a cell's value, starting a row update, etc.  Retry interval is a rough function based on hbase.client.pause.
 At first we retry at this interval but then with backoff, we pretty quickly reach  retrying
every ten seconds.  See HConstants#RETRY_BACKOFF for how the backup ramps up.  Change this
setting and hbase.client.pause to suit your workload.
> {quote}
> However, the semantic of this conf is confusing and different in various branches. After
HBASE-14521, in master it means "the number of RETRIES", but in all the other branches it
still means "the number of TRIES".
> So I think we need make the doc clearly and tell users what it is in 0.98/1.x and what
it will be from 2.0
