    I have a running cluster, and I want to update the mapreduce compression properties :
    – = true
    – =
    – mapred.output.compress = true
    – mapred.output.compression =

    Is there a way to do this configuration using Ambari ? I cannot see these parameters in mapred-site.xml and the checkbox of “Snappy compression” is disabled in Ambari :-(

    Thanks for any help !

    Hi, Bruno,

    What you can do is to put the value into the Custom MapReduce Configs under mapreduce advanced config.

    Hope this helps
