-----------------------------------------
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.
