> Support splitting BlockReport of a storage into multiple RPC
> ------------------------------------------------------------
>
> Key: HDFS-9011
> URL: https://issues.apache.org/jira/browse/HDFS-9011
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Jing Zhao
> Assignee: Jing Zhao
> Attachments: HDFS-9011.000.patch, HDFS-9011.001.patch
>
>
> Currently if a DataNode has too many blocks (more than 1m by default), it
> sends multiple RPC to the NameNode for the block report, each RPC contains
> report for a single storage. However, in practice we've seen sometimes even a
> single storage can contains large amount of blocks and the report even
> exceeds the max RPC data length. It may be helpful to support sending
> multiple RPC for the block report of a storage.
