Subject Re: when use broadcast variable and run on bigdata display this error please help
Date Thu, 20 Aug 2015 10:21:13 GMT
Because the broadcasted variable is completely stored at each operator. 

If you use a hash join, then both inputs can be hash partitioned. This reduces the amount
of memory needed for each operator, I think.
