Subject The slot in which the task was scheduled has been killed (probably loss of TaskManager)
Date Wed, 15 Apr 2015 12:42:20 GMT
Hi to all,

I have this strange error in my job and I don't know what's going on.
What can I do?

The full exception is:

The slot in which the task was scheduled has been killed (probably loss of
TaskManager).
