Peter Bacsko commented on MAPREDUCE-6201:
-----------------------------------------
I was thinking of the following approach:
1) Increase disk utilization percentage.
2) Before we verify the number of active trackers, check if the node status is
{{UNHEALTHY}} or not. If it is, then we explicitly show this in an error
message with a hint that the issue might be related to the lack of disk space.
Certainly we can verify the amount of free space but I think it would make the
test just more complicated. To me this solution looks safe.
