Hi All, 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.
<property> <name>mapreduce.tasktracker.map.tasks.maximum</name> <value>1</value> </property> <property> <name>mapreduce.tasktracker.reduce.tasks.maximum</name> <value>1</value> </property> Is there some other property i need to set for YARN? -- Thanks & Regards, Anil Gupta
