Cannot run program "null/bin/hadoop"
I have identified the problem.
I was using the "embedded" connection. The Talend's job was showing the connection was fine but in the reality the generated Java code had a connection string, omitting my host and port specified in the settings. As a result, Talend was trying to execute a HIVE query locally on my Windows machine.
Why is "embedded" wrong? Why the tool pretends the HIVE remote connection worked fine? Why it tries to run HIVE query locally even though I have specified the remote host and the port? I would consider it a bug...
