Hi, The first container in the application logs usually contains the gam logs. But the first container logs are not available. Hence no gam logs. What could be the possible reasons for the dying of some workers?

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](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
