Brandon Li created HDFS-4453:
--------------------------------
Summary: Make a simple doc to describe the usage and design of the
shortcircuit read feature
Key: HDFS-4453
URL: https://issues.apache.org/jira/browse/HDFS-4453
Project: Hadoop HDFS
Issue Type: Sub-task
Components: datanode, hdfs-client
Reporter: Brandon Li
It would be nice to have a document to describe the configuration and design of
this feature. Also its relationship with previous short circuit read
implementation(HDFS-2246), for example, can they co-exist, or this one is
planed to replaces HDFS-2246, or it can fall back on HDFS-2246 when unix domain
socket is not supported.
