Hi Hadoop users, I am new member and please let me know if this is not the correct format to ask questions.
I am trying to setup a small Hadoop cluster where I will run Pig queries. Hadoop cluster is running fine but when I run a pig query it just hangs. Note - Pig runs fine in local mode So I narrowed down the errors to the following - I have a secondary name node on a different machine (.e.g node 2). Point 1. When I execute start-mapred.sh on node 2, I get "ssh_exchange_identification closed by remote host" message. BUT the secondary name node starts with no error messages in the log I can even access it through port 50030 So far no errors Point 2. When I try to run a map-reduce job. I get a "java.net.ConnectException: Connection refused" error in the secondary name node log files. Are point 1 and point 2 related Any hints / pointers on how to solve this ? Also, ssh time out is set to 20 so I am assuming that error is not because of this. Thanks for reading -- Warm Regards Atul
