I don't understand the issue. Could someone help me? The master and slave are correctly set up as far as i can see. Thanks in advance!

Answer 1

This is a two-year old question, but for what it's worth, I had the same thing happen to me. I fixed it by removing the slave and then adding it back in. It was previously add and the log file showed it, so not sure what was wrong. At any rate, if this happens to anyone, give that a try.

Answer 2

I kill the java process and tried again with success.

Answer 3

Turned out to be an SSH permission denied issue for me. I discovered that by disconnecting and relaunching the node.
