Please check your cat /etc/ambari-server/conf/log4j.properties file to find out the correct path for your log files.

The best place to start is the ambari-server logs. These can usually be found on:

/var/log/ambari-server/ambari-server.log

Try to look at these logs (commands cat,less,more,etc) around the time that your ambari-server is going down to find more details

@Pedro Andrade @amarnath reddy pappu @Akhil S Naik - thanks for your quick reply.

I am seeing below statements repeatedly. unable to get exact error phrase/word. any help please . thanks in advance

[ambari-client-thread-9015] StackAdvisorRunner:** - Stack-advisor output=/var/run/ambari-server/stack-recommendations/2/stackadvisor.out, error=/var/run/ambari-server/stack-recommendations/2/stackadvisor.err

Rest all statements are INFO/WARN no error.

@Sankar T

Those are stack advisor error/messages. do you see stack trace in ambari-server log? usually stack advisor runs on config change and advise - some times that operation may fail.

[#7]

@amarnath reddy pappu

- I don't see a log during failed period.

is there a way to know why logs are not written ?

[#8]

@Sankar T stack advisor error should not bring down the cluster. check ambari-server.out log to see any errors

[#9]

Ambari is not writting any log information. even ambari-server.out is also not having error log for that period.
