Jing Zhao updated HDFS-9011: ---------------------------- Status: Patch Available (was: Open) > 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 > > > 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)
