Describe the bug

Hadoop exploiter somehow queues up multiple monkey executions and launches them one after each other.

To Reproduce

Steps to reproduce the behavior:

  1. Exploit machine with hadoop exploiter
  2. Observe that monkey binary was launched more times than machine was exploited

Expected behavior

Hadoop should only run monkey once for each exploitation

Hadoop: Disable speculative execution in YARN job
98f078b 
Hadoop's speculative execution feature has lead to a number of
difficulties. See #655, #1781, and #2578. Of concern is that the issue
where Hadoop sends a SIGKILL to the first process (#2578) could cause
significant issues when implementing agent OTP authentication (#3077).

Setting max-app-attempts to 1 resolves these issues.
