-----------------------------
Summary: CLONE - Erasure Coding: client generates too many small packets when writing parity data
Key: HDFS-10134
URL: https://issues.apache.org/jira/browse/HDFS-10134
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: dragon
Assignee: Li Bo
Fix For: HDFS-7285
Typically a packet is about 64K, but when writing parity data, many small packets with size 512 bytes are generated. This may slow the write speed and increase the network IO.
