[#2]

your /etc/hosts file should be like this 

192.168.121.11      cluster1

also change your hostname to cluster1 

/etc/hostname 

finally if its a test enviroment either disable the firewall or change the rules accordingly . 

this should fix you the problem. 

are you configuring single or multi node cluster ?

[#3]

I am configuring for single node only. I am new to the ubuntu system so can u please tell me what is the difference between single node and multi node.

Also in /etc/hosts i have to remove all the configuration and just put: 

x.y.z.a  cluster1

127.0.0.1 is not required in /etc/hosts file ??????

Currently my /etc/hosts file is like this:

My /etc/hosts file is:

127.0.0.1         localhost

#127.0.0.1       PC355406

10.x.y.z            PC355406

# The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

Kindly help me in that.

[#4]

single node cluster - you will have all the service under one host mostly for testing purpose . 

multi node cluster  - you will have many host each one will have their own dameon runining for example 

node1  will have master service like - namenode , YARN 

node 2 will have impala daemons 

node 3 will have hive server2 

node 4 - can acts edge nodes 

to make it simple for a single node cluster configure like this 

/etc/hosts 

any ip address like (192.168.121.14)    server1 

/etc/hostname will have 

server1 

exit the terminal or reboot the system - make sure you have your hostname configured properly by typing 

echo $hostname.

hi,

i have tried the solution you suggested but still i got sam error.

i have disabled iptables,

i have also put use_tls=1 in the file /etc/cloudera-scm-agent/config.inihas

what else i can do to solve this problem  and how to do that as i am new to this environment??

Thanks in advance for helping me..

[#6]

tell me what you have under your cloudera manager ini 

in the 

[general ] 

server_host, server_port, listening_port, listening_hostname

also whats you hostname that you had configured.

# The certificates in the directory are only looked up when required, e.g. when

# building the certificate chain or when actually performing the verification

# without an agent restart.

# When looking up CA certificates, the verify_cert_file is first searched, then

# those in the directory. Certificate matching is done based on the subject name,

# the key identifier (if present), and the serial number as taken from the

# certificate to be verified. If these data do not match, the next certificate

# will be tried. If a first certificate matching the parameters is found, the

# verification process will be performed; no other certificates for the same

# parameters will be searched in case of failure.

# verification will not be performed.

and my hostname is amit.

and /etc/hosts file has:

Kindly tell me where i am doing mistake.

Hi,

As due to unknown reasons i'm unable to post my complete error logs in my message, i've attached a link to log. Please have a look on error log.

Thank You
Amit

[#9]

i see that your host file has xxx yy something 

my etc/hosts file contains:
xx.yyy.zz.aaa     amit

and my hostname file contains:
amit

you should have some meaning full ip add like 192.168.138.2 

[#10]

the ip address is 10.239.39.115

Is there is anything where i need to do some changes to keep things going.

Thanks,
Amit
