> Currently Tez AM size is increased upto 4G automatically based on total
> number of tasks. Also need to take into account a lot of other factors like
> vertices, number of shuffle edges possible, etc.
> A job with 17390 tasks for which memory was increased to 2G and container
> size to 2.5G still failed with OOM as it had 38 vertices.
