Record DFS client/cli id with username/kerbros session token in audit log or
hdfs client trace log
--------------------------------------------------------------------------------------------------
Key: HDFS-1455
URL: https://issues.apache.org/jira/browse/HDFS-1455
Project: Hadoop HDFS
Issue Type: New Feature
Reporter: Eric Yang
HDFS usage calculation is commonly calculated by running dfs -dus and group
directory usage by user at fix interval. This approach does not show accurate
HDFS usage if a lot of read/write activity of equivalent amount of data happen
at fix interval. In order to identify usage of such pattern, the usage
calculation could be measured by the bytes read and bytes written in the hdfs
client trace log. There is currently no association of DFSClient ID or CLI ID
to the user or session token emitted by Hadoop hdfs client trace log files.
This JIRA is to record DFS Client ID/CLI ID with user name/session token in
appropriate place for more precious measuring of HDFS usage.
