We can try finding out which data is becoming unexpectedly large by running the ambari agent in debug mode. For that we can edit the following file "/etc/ambari-agent/conf/ambari-agent.ini" and edit the following line to DEBUG:

loglevel=INFO

Change it as following:

loglevel=DEBUG

.

Then when we try to restart ambari agent then it should show the agent registration request (JSON Data).

We can grep the following entry:

# ambari-agent stop
# ambari-agent start
# grep 'Registering with' /var/log/ambari-agent/ambari-agent.log.*

.

@white wartih

hosts table of ambari DB has 255 column size for different columns which is OK in most scenarios. However in your case looks like some host specific data is too large.

In an other thread one user reported similar issue when the MAC address was being generated in junk (too large) , Can you please check:

thank you very much ! it turns out that our company's network is running in a wrong way.and we can reach "169.254.****", and we get a public_host_name which is a strange html,this html is too long for the var "public_host_name". In the situation we speculate,this address could not be reached.and it throws an exception to make the var getting the local host.too strange to understand T T

the file's location:

/usr/lib/python2.6/site-packages/ambari_agent/hostname.py

method name: public_name
