[jira] [Commented] (MAPREDUCE-6201) TestNetworkedJob fails on trunk

["Peter Bacsko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15958959#comment-15958959 ] 

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.
