-----------------------------------
Assignee: Shuyan Zhang
> Reduce the number of HeartbeatManager loops
> -------------------------------------------
>
> Key: HDFS-16735
> URL: https://issues.apache.org/jira/browse/HDFS-16735
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Shuyan Zhang
> Assignee: Shuyan Zhang
> Priority: Major
>
> HeartbeatManager only processes one dead datanode (and failed storage) per
> round in heartbeatCheck(), that is to say, if there are ten failed storages,
> all datanode states need to be scanned 10 times, which is unnecessary. This
> patch makes the number of bad storages processed per scan configurable.
