reading Hadoop output messages
Hi all,
I'm wondering if there is a way to get output messages that are printed
from the main class of a Hadoop job.
Usually "2>&1>> out.log" would wok, but in this case it only saves the
output messages printed in the main class before starting the job.
What I want is the output messages that are printed also in the main class
but after the job is done.
For example: in my main class:
try {JobClient.runJob(conf); } catch (Exception e) {
e.printStackTrace();} //submit job to JT
sLogger.info("\n Job Finished in " + (System.currentTimeMillis() -
startTime) / 60000.0 + " Minutes.");
I can't see the last message unless I see the screen. Any ideas?
Thank you,
Mark
