How to control what goes into Hadoop logs?
Hi,

My Hadoop cluster runs log with the level of INFO, and it outputs every
block-related information to the HDFS log. I would like to keep the INFO
level, but suppress block-related information. Is it possible? Can one
control Hadoop logs by components?

Thank you. Sincerely,
Mark
