Hello , i set up 2 datanodes on a single machine(ubuntu machine) accordingly mentioned in the thread http://mail-archives.apache.org/mod_mbox/hadoop-common-user/201009.mbox/%3ca3ef3f6af24e204b812d1d24ccc8d71a03688...@mse16be2.mse16.exchange.ms%3E
Ubuntu machine has 2 processors and 8 cores. Assuming that machine is powerful , i Setup 2 datanodes on that same machine. Now when i run jps on that multinode hadoop , i get Namenode Datanode Datanode Jobtracker Tasktracker Secondary Namenode The above result Shows 2 datanodes are up and running Also i have a single node on that ubuntu machine as well. Now when i check Performance on singlenode and multinode , both are almost same.So now , How do i make sure load is being distributed on both datanodes or each datanode uses different cores of the ubuntu machine. (Note: i know multiple datanodes on same machine is not that advantageous , but assuming my machine is powerful ..i set it up..) would appreciate any advices on this. Regards, Sindhu
