I am working with a programm that map output is nearly 100Gigabyte.i have a mapr cluster with 5 tasktrackers. I want to compress output. I have set mapred.compress.map.output=true in the tasktrackers mapred-site.xml but the shuffle size didn't change.
Does mapr reduce shuffle size authomaticly? i have set mapreduce.maprfs.use.compression=false, but the shuffle size didn't change!!
How can i compress map output in mapr?
Thanks.
