Subject Re: output worker stdout to one place
Date Fri, 20 Feb 2015 19:37:38 GMT
Hi Anny,

You could play with creating your own log4j.properties that will write
the output somewhere else (e.g. to some remote mount, or remote
syslog). Sorry, but I don't have an example handy.

Alternatively, if you can use Yarn, it will collect all logs after the
job is finished and make them available as a single file using the
"yarn logs" command.
