FAQ
Hi Alan:

See my attached picture. For example, if I want to check the namenode role
log file, I go:
"Services" -> "Service hdfs1" -> "Instance" tab, then choose "namenode".
"Role Log Details" is highlighted.

What service did you try to start? If you can't find the log file in the
UI, can you just post it here?

For me, the log file of namenode service is located at:
/var/log/hadoop-hdfs/hadoop-cmf-hdfs1-NAMENODE-hadoop1.domain.log.out

Thanks

Hi Tony,

I am sorry I could not locate the log based on navigation path you
specified below. I opened system validation messages (small icon on right
corner) , it says no host heartbeat.

When I pined node1 and manager , it says 0% packet loss.
Does this info help? please let me know.. if you have a screen shot to
find log below, then it wil be of great help
Thanks

Hi Alan:

Which service did you try to start? So you can log into CM without any
problem, right? Can you also check the service's log file see if there any
specific errors?
"Services->Instances->Role Instances (Choose a role)-> Role Log Details"

Hi team ,

I am new to Hadoop world. I am trying to set up single node cluster on
my laptop. I have installed 2 VMs on my machine. The first one is hosting
the cloudera manager . I am planning to use this instance to access
your cluster, monitor it, configure it, add some nodes, etc. This will be
you main access to your cluster.

The second VM is your first node. This is where all the hadoop related
applications run.As there is only one node at the beginning, all the
roles/applications are running on this single node.

Here are few steps that I followed -

1. Import the 2 VMs into VirtualBox and start them
2. Configure the network


The users on the VMs are root and user.

On the node1 VM, login as root and i used command "ifconfig" to get the
IP address..

First, i removed the hosts file using "rm /etc/hosts". And added the
hosts back to the file using "echo 1XX.XXX.1.1 manager >> /etc/hosts"
by replacing 1XX.XXX.1.1 with my manager IP. I did the same thing for
node1. "echo 1XX.XXX.1.2 node1 >> /etc/hosts" by replacing again the IP
address with the node1 IP address. And last add localhost "echo
12X.X.X.1 localhost >> /etc/hosts".


Then I did from manager console, type "ping -c 1 node1". and it said ,
0 % packet loss. Then same thing from node1 ,I typed "ping -c manager".
and it said 0% packet loss.


After that , I used cat /etc/hosts command on node1 and manager VM , it
shows in total three IP addess as follows

1XX.XXX.1.1 manager

1XX.XXX.1.2 node1

12X.X.X.1 localhost


I also see that I connected to user@node1 and root@manager terminals .


Now when I try to start services from firefox icon on manager VM, system
throws following error - "Command aborted because of exception : Command
timed-out after 150 seconds".


Can someone please help with this issue ? It will be of great help

Thanks
Allan
