Summary: Change DN to send block receipt IBRs in batches Key: HDFS-9710 URL: https://issues.apache.org/jira/browse/HDFS-9710 Project: Hadoop HDFS Issue Type: Improvement Components: datanode Reporter: Tsz Wo Nicholas Sze Assignee: Tsz Wo Nicholas Sze When a DN has received a block, it immediately sends a block receipt IBR RPC to NN for report the block. Even if a DN has received multiple blocks about the same time, it still sends multiple RPCs. It does not scale well since NN has to process a huge number of RPCs when many DNs receiving many blocks at the same time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
