You can enable log-aggregation where-by your application logs will be uploaded to HDFS.

Overview here:

Configurations from http://hadoop.apache.org/docs/r2.0.4-alpha/hadoop-project-dist/hadoop-common/ClusterSetup.html
which are relevant are:
yarn.log-aggregation-enable -> true
yarn.nodemanager.remote-app-log-dir -> /logs (directory on hdfs which will need to be created
before you start your cluster)
