----------------------------------
Summary: XORShiftRandom.setSeed allocates unnecessary memory

Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.3.0
Reporter: Maxim Gekk
The setSeed method allocates 64 bytes buffer and puts only 8 bytes of the seed
parameter into it. Other bytes are always zero and could be easily excluded
from hash calculation.
