Re: hdfs cannot start

Dear all,

I am using CM 4.1, it was working properly. But as suggested if I will
close the host, I have to stop all the services. So I did so.

Do anyone has a solution to this problem ?

I am now trying to start the services, I got this error :

Service did not start successfully; not all of the required roles
started: Service hdfs1 does not have sufficient running NameNodes.


Do anyone has a solution to this problem ?

While checking the namenode, I found this exception:

Command aborted because of exception: Command timed-out after 150 seconds

Hi Dalia,

Sorry, I was mistaken - though it appears that you found the right file -
should be the contents of *.log.out

You've sent me the contents, which make me think of a few issues:
1) these logs are from November 21 - has anything happened since then??
2) What is your /etc/hosts file please

p.s. please include scm-users@ on your replies in case other folks have
insight

Thanks,
Adam

/etc/hosts:

cat /etc/hosts
127.0.0.1 localhost
192.168.2.3 master1.medcloud.com
# 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

nothing happened it worked normally, so its weird that I didn't see my
trials for today in log files.

I checked all the log files concerning hdfs
/var/log/hadoop-hdfs/hadoop-cmf-hdfs1-*-master1.medcloud.com.log.out
Their last record was 25-11 and everything was working normally.
I feel there is a problem in connection, although ssh is working properly

This typically means that the agent isn't heartbeating. If you go to the
'hosts' tab, do you see the hosts heartbeating in?

That means that the agent process isn't running on the host, or is
otherwise failing. Try "sudo service cloudera-scm-agent start" and look in
the logs in /var/log/cloudera-scm-agent/*.
