I'm using giraph-1.3 built with yarn profile. For starting I configured 1 namenode and 2 datanodes on a ec2 cluster. My application properly works, I launched giraph with -w 2 because I have two datanodes.
In userlogs of datanode1 I found log of first worker. in userlogs of datanode2 I found log of second worker and log of master too. I expected to find log of master in the namenode i.e. I expected that master runs on namenode. Is it right? Maybe I have to configure another datanode and then I will find master logs on this new datanode? -- Cristina Bovi
