HDFS metrics log to the same filename from both namenode and secondary namenode
-------------------------------------------------------------------------------
Key: CHUKWA-443
URL: https://issues.apache.org/jira/browse/CHUKWA-443
Project: Hadoop Chukwa
Issue Type: Bug
Components: input tools
Environment: Redhat EL 5.1, Java 6
Reporter: Eric Yang
Assignee: Eric Yang
Fix For: 0.4.0
In hadoop-metrics.properties template file, the hdfs metrics is configured to
log to CHUKWA_LOG_DIR/metrics/<username>-dfs-metrics.log. If the user has both
namenode and secondary namenode running on the same machine, the metrics are
logged to the same filename. The default template should use uuid flag to
distinguish the metrics for different processes.
