I have installed hadoop on 3 nodes, 1 master and 2 -slave nodes. on master node and one of slave node is having same hadoop path i.e. /home/hduser/hadoop, but in one slave node it is different, i.e. /usr/hadoop
so while running ./start-all.sh from master namenode and jobtarcker started, and datanode started on one slave that is having same hadoop path as master node,but on other slave node it is giving error like--
ngs-dell: bash: line 0: cd: /home/hduser/hadoop/libexec/..: No such file or directory
means it is searching on same path as master, but it have different path.
Please tell me how to solve this issue.
And one more doubt, is it compulsary that all hadoop node (master & slave) should have same username, in my case it is hduser. If I change on one node of hadoop cluster then it gives me error.
