Robert Kanter commented on OOZIE-1560:
--------------------------------------

Test failure is unrelated and seems to be flakey (created OOZIE-1568 for it).

> Log messages should have a way of identifying which server they came from 
> when using HA

> When using HA, the only way to know which server is processing a specific job 
> is to go into each server's log file and look for log messages about that 
> job; when looking at the logs from the API, there is no way to know.  
> This information can be useful, so it would be good to add the server name as 
> part of the log message.  This can either be done for logs permanently or can 
> be done when a server is aggregating/collating logs from the other servers.  
> The former is probably more efficient than the latter.  If we go with the 
> former, I'd say that we should always do it, regardless of HA so the log 
> formatting is consistent and in case that server is added to an HA group 
> later.
> For example, instead of this:
> {noformat}
