Hi guys : im getting the dreaded org.apache.hadoop.ipc.Client$Connection handleConnectionFailure
When connecting to clouderas hadoop (running in a vm) to request running a simple m/r job (from a machine outside the hadoop vm)...... ....I've seen a lot of posts about this online, and it's also on stack overflow here : http://stackoverflow.com/questions/6997327/connecting-to-cloudera-vm-from-my-desktop Any tips on debugging Javas connection to hdfs over the network? It's not entirely clear to me how the connection is made/authenticated between the client and hadoop, for example, is a passwordless ssh file required..? I believe this error is related to authentication but am not sure the best way to test it... I have confirmed that the ip is valid And it appears that hdfs is being run and served over the right default port in the vm. Sent from my iPad
