Re: Datanodes failed to start the role because hdfs-sockets cannot be created

Hi,

 

I am facing the same issue.

I tried with both users: root and cloudera-scm to set as owners for /var/hdfs-sockets/dn.

Error is: Address already in use when trying to bind to '/var/hdfs-sockets/dn'

But without success.

Can someone please provide some hints on this?

 

Thanks

@VeljkoC,

 

I moved this post in front of the HDFS community members since it targets problem with HDFS rather than CM itself.

Can you provide the actions you took and evidence of what happened (provide logs and/or screenshots?)

 

Thanks!

@VeljkoC Are you using cloudera manager?

 

If yes, can you check the hdfs configuration for UNIX Domain Socket path, what is it value?

 

If it empty try to add : /hadoop/sockets/hdfs-sockets/dn
