The error message points that the permissions on worker-launcher binary are not correct. Please check that the permissions on worker-launcher binary. It should be owned by root:hadoop or the group parameter configured in worker-launcher.cfg.

From the log message it appears that the group ownership is root.

Also note that the permissions on the binary should be 6550 else it would fail again after you change the group ownership. Here is the output of the ownership from my test system.
