tao updated SPARK-21118:
------------------------
Description:
i have 2 matrix each one is 200milions*200milions.
i want to multiply them ,but run out with oom .
finally i find the oom appear at blockmatrix.simulateMultiply . there is a
collect action at this method. when application run there the driver will oom.
class BlockMatrix @Since("1.3.0") (
private[distributed] def simulateMultiply(
other: BlockMatrix,
partitioner: GridPartitioner): (BlockDestinations, BlockDestinations) = {
val leftMatrix = {color:red}blockInfo.keys.collect() {color}// blockInfo
should already be cached
val rightMatrix = other.blocks.keys.collect()
......
