I am using spark engine for cube processing, step to Convert Cuboid Data to HFile is taking most of time. 14 M input record, 3 dimensions ( 1 UHC) , it took around 28 mins to build the cube out of which 20 mins just for Convert Cuboid Data to HFile. I noticed this step is running map reduce even though I have selected spark as engine type. is there any way to make this step run on spark instead of MR ? also there any configuration which can help to optimize this step?
