Cloudera manager 5.5 install : HDFS error

New Contributor

Hi,

 

I'm trying to install  a single node cluster with the cloudera manager installer.

 

Everything goes smoothly until Cluster Setup fails at the "Start HDFS" step with the error "Failed to format NameNode".

 

On the same screen when clicking the "Full log file" link I get a popup with :

 No such file or directory: '/var/log/hadoop-hdfs/hadoop-cmf-hdfs-NAMENODE-myhost.log.out'

 

I checked the dfs.namenode.name.dir property, it has two values "/data/dfs/nn" and "/soft/dfs/nn", both of these directories seem to have suficient permissions:

 

# ll /data/dfs
drwx------ 2 hdfs hadoop 4096 Jan 12 10:57 nn
# ll /soft/dfs
drwx------ 3 hdfs hadoop 4096 Jan 11 16:14 dn
drwx------ 3 hdfs hadoop 4096 Jan 11 16:14 nn

 

I also checked the log directory permissions (for the popup error message), they are as follows:

 

# ll /var/log
drwxrwxr-x 4 hdfs   hadoop  4096 Jan 12 11:11 hadoop-hdfs

 

Here are logs I got in cloudera-scm-agent.log when hitting the Retry button :

At this point I would be very grateful if someone could point me in the right direction.

 

Thanks

Found the issue, it was partially me not reading the log carefully enough.

 

The log from my first post mentions directory "/var/run/cloudera-scm-agent/process/20-hdfs-NAMENO​DE-format/logs", in which I found stderr.log with the lines :

Running in non-interactive mode, and data appears to exist in Storage Directory /soft/dfs/nn. Not formatting.
16/01/12 11:15:37 INFO util.ExitUtil: Exiting with status 1

 

 

It turns out there were files remaning from a previous attempt, cleaning them solved the issue.
