-------------------------------
Summary: Support observer reads for WebHDFS
Key: HDFS-13152
URL: https://issues.apache.org/jira/browse/HDFS-13152
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, namenode, webhdfs
Reporter: Chao Sun
In the case of WebHDFS, a designated DN will launch a DFSClient and stream data
to the WebHDFS client. The DFSClient will read the local configuration files
(e.g., hdfs-site.xml) on the DN. So, in this case changes may be required for
WebHDFS to enable observer reads.
