Re: what does Submitting ... missing tasks from Stage mean?

Thanks Imran, but I do appreciate if you explain what this mean and what
are the reasons make it happening. I do need it.
If there is any documentation somewhere you can simply direct me there so
 I can try to understand it myself.

 yeah, this is just the totally normal message when spark executes
 something.  The first time something is run, all of its tasks are

 if you're new to spark, its probably an advanced concept that you don't
 care about.  (and would take me some time to explain :)

 Hi,

 Probably this is silly question, but I couldn't find any clear
 documentation explaining why  one  should submitting... missing tasks from
 Stage ... in the logs?

 Specially in my case when I do not have any failure in job execution, I
 wonder why this should happen?
 Does it have any relation to lazy evaluation?
