You are probably looking at your giraph application manager (gam) logs. You should look for your workers logs, each one have a log (container's logs). If you can't find them, you should look at your yarn configuration in order to know where are them, see this: http://stackoverflow.com/questions/21621755/where-does-hadoop-store-the-logs-of-yarn-applications .
I don't recommend you to enable checkpointing until you now the specific error that you are facing. If you are facing out of memory errors for example, checkpointing won't be helpful in my experience, the same error will happen over and over. -- *José Luis Larroque* Analista Programador Universitario - Facultad de Informática - UNLP Desarrollador Java y .NET en LIFIA 2017-02-25 12:38 GMT-03:00 Sai Ganesh Muthuraman <saiganesh...@gmail.com>: > Hi Jose, > > Which logs do I have to look into exactly, because in the application > logs, I found the error message that I mentioned and it was also mentioned > that there was *No good last checkpoint.* > I am not able to figure out the reason for the failure of a worker for > bigger files.
