Logging for MR Job

[Joel Alexandre <jo...@gmail.com>]

hi,

i'm running some Hbase MR jobs through the bin/hadoop jar command line.

How can i change the log level for those specific execution without
changing hbase/conf/log4j.properties ?

I'm my jar there is a log4j.properties file, but it is being ignored.

Thanks,
Joel

Your log4j.properties is in the right location inside the job jar?  (

Did you try passing in the log level via  generic options?
E.g. I can switch the log level of a running job via:
hadoop jar hadoop-mapreduce-examples.jar pi *-D
mapred.map.child.log.level=DEBUG *10 10
hadoop jar hadoop-mapreduce-examples.jar pi *-D
mapred.map.child.log.level=INFO* 10 10

Worst case you can modify the log level directly into your code?
