Balaji Rajagopalan commented on MAPREDUCE-1854:
-----------------------------------------------
What about getting rid of the script wrappers for ssh functionality and sleep?
I will come with script wrapper for copying and deleting the script files in
remote nodes, but you do see the need to have sleep and echo ERROR message in a
script, this is because tasktracker code picks up a health script and runs it
in regular interval which is configurable. So to induce the error I change the
health script location, and copy the error inducing health script, and put back
everything to normal state at the end of the test. So I don't think I can do
script wrapper for sleep, echo error.

> 1. There are three scenarios, first is induce a error from health script,
> verify that task tracker is blacklisted.
> 2. Make the health script timeout and verify the task tracker is blacklisted.
> 3. Make an error in the health script path and make sure the task tracker
> stays healthy.
