-mapreduce.tasktracker.map.tasks.maximum property not working with YARN
I have a hadoop2.0.0-alpha hadoop/hbase cluster runnning on CentOS6.0. The
cluster has 4 admin nodes and 8 data nodes. I would only like run one
mapper/reducer at a time on each nodemanager. For doing that i had set the
following properties in my mapred-site.xml. However setting this property
is not having any impact on YARN, YARN is running simultaneously 8 map
tasks on one NodeManager.
Is there some other property i need to set for YARN?
Thanks & Regards,
