Hi there: I got an problem that "Application has been killed.Reason:All masters are unresponsive!Giving up." I check the network I/O and found sometimes it is really high when running my app. Pls refer to the attached pic for more info.I also checked http://databricks.gitbooks.io/databricks-spark-knowledge-base/content/troubleshooting/connectivity_issues.html, and set SPARK_LOCAL_IP in every node's spark-env.sh of my spark cluster. However it does not benifit in solving this problem.I am not sure if this parameter is correctly set,my setting is like this:On node1:export SPARK_LOCAL_IP={node1's IP}On node2:export SPARK_LOCAL_IP={node2's IP}......
BTW,I guess that the akka will retry 3 times when communicate between master and slave, it is possible to increase the akka retries? And except expand the network bandwidth, is there another way to solve this problem? thanks for any coming ideas. -------------------------------- Thanks&Best regards! San.Luo
