------------------------------------------------------------------

When replication is down, say because of a network partition or temporary issue 
on one cluster, RPC calls cannot succeed and will time out. However once the 
network or cluster is back in operation we want replication activity to resume 
as quickly as possible. Does this change prevent timely restart of replication 
activity? Won't we potentially be waiting for a long time for the current call 
to timeout before probing with another attempt? Would the time we might wait 
unnecessarily increase as the duration of the outage increases, making a long 
outage a really really long outage?

> When peer cluster replication is disabled and lot of writes are happening in 
> active cluster and later on peer cluster replication is enabled then there 
> are chances that replication requests to peer cluster may time out.
> This is possible after HBASE-13153 and it can also happen with many and many 
> WAL data replication still pending to replicate.
> Approach to this problem will be discussed in the comments.
