No Response when running program on Spark on EC2 Cluster

[尹志军]

Hi,

I followed instructions in the document of 0.8.1 to run a program on EC2 cluster. 

1. I can setup the cluster and the program can run successfully on master node in local mode. 

2. When I start my program in cluster mode, the information on std tells me that the process has been run, and then no response. Just stay there.

3. My program just reads a file from the HDFS in master node and then prints out the number of the lines in the file. 

4. I check the Web UI and find that the process is finished and uses 0 memory. 

Could you please give me a hint?

Thanks

Best,

Zhijun
