-----------------------------------
Summary: Add Tracing to HDFS
Key: HDFS-5274
URL: https://issues.apache.org/jira/browse/HDFS-5274
Project: Hadoop HDFS
Issue Type: New Feature
Components: datanode, namenode
Reporter: Elliott Clark
Assignee: Elliott Clark
Since Google's Dapper paper has shown the benefits of tracing for a large
distributed system, it seems like a good time to add tracing to HDFS. HBase
has added tracing using HTrace. I propose that the same can be done within
HDFS.
