Unable to start YARN - NodeManager on role NodeManager

avatar
Explorer

 

Execute command Start this NodeManager on role NodeManager 

Failed to start role

Supervisor returned FATAL. Please check the role log file, stderr, or stdout.

 

Environment details:

 

Version: Cloudera Express 5.15.0
Java VM Name: Java HotSpot(TM) 64-Bit Server VM
Java VM Vendor: Oracle Corporation
Java Version: 1.7.0_67
 
System details:
Linux optim-rhel72-uppu.development.unicomglobal.software 3.10.0-327.28.3.el7.x86_64 #1 SMP Fri Aug 12 13:21:05 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux

 

I have followed the steps under "Configuring TLS/SSL for HDFS, YARN and MapReduce" using the link https://www.cloudera.com/documentation/enterprise/5-15-x/topics/sg_hive_encryption.html
 
Service did not start successfully; not all of the required roles started: only 0/1 roles started. Reasons : Service has only 0 NodeManager roles running instead of minimum required 1

I see below error in the role log:

Thanks,

Is nosuid set on the mount point?  I had a simialr issue documented here: http://community.cloudera.com/t5/Cloudera-Manager-Installation/URGENT-Cluster-unavailable-after-upgr...

This is the content of my /etc/fstab file

/dev/mapper/rhel_rhel72-root /                       xfs     defaults        0 0

/dev/mapper/rhel_rhel72-swap swap                    swap    defaults        0 0

Do I need to change anything?

Hi Li,

 

Thanks for being on top of it and helping me in solving the problem.

 

usermod -g yarn yarn

usermod -a -G hadoop yarn

 

Above two commands fixed my problem.

[root@optim-rhel72-uppu meta]# id yarn
uid=1007(yarn) gid=1008(yarn) groups=1008(yarn),1010(hadoop)

 

I have no idea how yarn user permissions are changed, all that I am following is that what have been suggested in cloudera instructions to enable encryption.

 

Thanks to all of the folks for providing suggestions.

 

Problems like this sucks lot of time in identifying where to fix and I would request cloudera to improve such situations.

 

Thanks,

Tulasi

Hi @Tulasi,

 

Try to kill running process on port used by Yarn Services and then Try to restart.
