Description

HIVE-18866 introduced a fast-path for integer -> murmur hash, but the change hasn't been applied to BloomKFilter for integers.

public class BloomKFilter {
  private final byte[] BYTE_ARRAY_4 = new byte[4];
  private final byte[] BYTE_ARRAY_8 = new byte[8];

Remove these objects and use the fast-path.
