> In distributedLogReplay(hbase-7006), we allow writes even when a region is in recovering.
It may cause undesired behavior when applications(or deployments) already are near its write
capacity because distributedLogReplay generates more write traffic to remaining region servers.
> The new config "hbase.regionserver.disallow.writes.when.recovering" tries to address
the above situation so that recovering won't be affected by application normal write traffic.
> The default value of this config is false(meaning allow writes in recovery)
