Jing Zhao created HDFS-9011: ------------------------------- Summary: 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
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
