Imran Rashid commented on SPARK-23433:
--------------------------------------
sorry it has taken me some time to get to this -- its a little more complex
than I thought as currently tasksetmanagers for the same stage do not send any
updates to each other, so I am trying to make sure I understand it well.
anyone else is welcome to take it up in the meantime.
[~guoxiaolongzte] -- are you sure you see the same issue, with the same
sequence of events as described by Shixiong Zhu? I want to make sure its not
another instance of the same exception, but perhaps with a different underlying
cause.
