> Don't transfer all the queued hlogs of a dead server to the same alive server

> URL: https://issues.apache.org/jira/browse/HBASE-12770
> Project: HBase

>
> When a region server is down(or the cluster restart), all the hlog queues
> will be transferred by the same alive region server. In a shared cluster, we
> might create several peers replicating data to different peer clusters. There
> might be lots of hlogs queued for these peers caused by several reasons, such
> as some peers might be disabled, or errors from peer cluster might prevent
> the replication, or the replication sources may fail to read some hlog
> because of hdfs problem. Then, if the server is down or restarted, another
> alive server will take all the replication jobs of the dead server, this
> might bring a big pressure to resources(network/disk read) of the alive
> server and also is not fast enough to replicate the queued hlogs. And if the
> alive server is down, all the replication jobs including that takes from
> other dead servers will once again be totally transferred to another alive
> server, this might cause a server have a large number of queued hlogs(in our
> shared cluster, we find one server might have thousands of queued hlogs for
> replication). As an optional way, is it reasonable that the alive server only
> transfer one peer's hlogs from the dead server one time? Then, other alive
> region servers might have the opportunity to transfer the hlogs of rest
> peers. This may also help the queued hlogs be processed more fast. Any
> discussion is welcome.
