@Shelton any update on this

Sorry festive period, can you do the following.
Delete old messages in /var/log/messages all that have the extension /var/log/messages.x that should leave you with only one /var/log/messages then truncate that file so you will have only new entries
# truncate --size 0 /var/log/messages
Do the same for /var/log/hadoop-yarn/yarn/hadoop-yarn-nodemanager-<node_name>.log.x and also truncate the /var/log/hadoop-yarn/yarn/hadoop-yarn-nodemanager-<node_name>.log
# truncate --size 0 /var/log/hadoop-yarn/yarn/hadoop-yarn-nodemanager-<node_name>.log
Start manually the node manager
# su -l yarn -c "/usr/hdp/current/hadoop-yarn-nodemanager/sbin/yarn-daemon.sh start nodemanager"
Then share the latest files created below
Please revert

I see in the hadoop-yarn-nodemanager-w0lxdhdp05.ifc.org.log errors pointing to "Unable to start NodeManager: Could not load library. Reasons: [no leveldbjni64-1.8 in java.library.path, no leveldbjni-1.8 in java.library.path, no leveldbjni in java.library.path, /var/lib/ambari-agent/tmp/hadoop_java_io_tmpdir/libleveldbjni-64-1-6279667856305652637.8 (Permission denied)]
My suspicion:
Please verify that /tmp on the host does not have the noexec option set. You can verify this by running /bin/mount and checking the mount options. If you are able to, remount /tmp without noexec and try starting the NodeManager again. I am sure its issue with noexec on /tmp.
See my sample output
[root@tokyo ~]# /bin/mount

proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)

/dev/sda10 on /u01 type ext4 (rw,relatime,data=ordered)
/dev/sda9 on /tmp type ext4 (rw,relatime,data=ordered)
This issue occurs when the user running the Hadoop [Nodemanager start] process does not have the necessary rights and cannot generate temporary files under the /tmp directory.
Solution
- Allow the user running node manager startup process read/write/execute access on /tmp
- Remove the noexec parameter when mounting /tmp
- Change the execution rights on /tmp. ie: sudo chmod 777 /tmp
In the /var/log/messages I can also see
Jan 2 05:14:23 w0lxdhdp05 abrt-server: Package 'ambari-agent' isn't signed with proper key
Jan 2 05:14:23 w0lxdhdp05 abrt-server: 'post-create' on '/var/spool/abrt/Python-2020-01-02-05:14:22-11897' exited with 1

Please edit /etc/abrt/abrt-action-save-package-data.conf change the value for OpenGPGCheck should be changed from yes to no.
OpenGPGCheck = no
It might also be necessary to change the value of limit coredumpsize:
limit coredumpsize unlimited
After editing the file restart the process with the following command:
# service abrtd restart
Restart the node manager and share your joy !

@Shelton As checked, the /tmp does not have noexec enabled. Please provide an alternate solution for this.
/dev/mapper/rootvg-tmp on /tmp type xfs (rw,relatime,attr2,inode64,noquota)

@Shelton Any update on this? looks like it is looking for some java packages
java.lang.UnsatisfiedLinkError: Could not load library. Reasons: [no leveldbjni64-1.8 in java.library.path, no leveldbjni-1.8 in java.library.path, no leveldbjni in java.library.path, /var/lib/ambari-agent/tmp/hadoop_java_io_tmpdir/libleveldbjni-64-1-4657625312215122883.8 (Permission denied)]
can we install it externally?
