Tsz Wo (Nicholas), SZE commented on HADOOP-3062:
------------------------------------------------
- Should we check whether ClientTraceLog.isInfoEnabled() before logging?
- Should we define an AUDIT_FORMAT for the log messages, like
FSNamesystem.AUDIT_FORMAT?
- I think it might worth to create a utility class, say
org.apache.hadoop.log.AuditLog, so that we could put AUDIT_FORMAT,
isInfoEnabled(), etc. inside it. Then, both DataNode and FSNamesystem can use
it.

> In order to better understand the relationship between hadoop performance and
> the network bandwidth, we need to know
> what the aggregated traffic data in a cluster and its breakdown by racks.
> With these data, we can determine whether the network
> bandwidth is the bottleneck when certain jobs are running on a cluster.
