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
