Lars Hofhansl commented on HBASE-12971:
---------------------------------------
[~amuraru], agreed.
[~apurtell], the default is max retries is 10 (i.e. 10s with the default sleep
interval). For socket timeouts that is too small (I think).
In fact I see the following comment as to why socket timeouts are handled
differently:
{code}
// This exception means we waited for more than 60s and nothing
// happened, the cluster is alive and calling it right away
// even for a test just makes things worse.
{code}
I do not see us setting a socket timeout anywhere, so the 60s much be an
assumption/default.
Maybe the retry after a socket timeout should at least wait for 60s. (i.e.
max(60s, sleep interval * max retries).

> We are setting in hbase-site the default value of 300 for
> {{replication.source.maxretriesmultiplier}} introduced in HBASE-11964.
> While this value works fine to recover for transient errors with remote ZK
> quorum from the peer Hbase cluster - it proved to have side effects in the
> code introduced in HBASE-11367 Pluggable replication endpoint, where the
> default is much lower (10).

> The the two default values are definitely conflicting - when
> {{replication.source.maxretriesmultiplier}} is set in the hbase-site to 300
> this will lead to a sleep time of 300*300 (25h!) when a sockettimeout
> exception is thrown.
