             Summary: BloomKFilter: Avoid using the local byte[] arrays entirely
                 Key: HIVE-20101
                 URL: https://issues.apache.org/jira/browse/HIVE-20101
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
    Affects Versions: 4.0.0
            Reporter: Gopal V


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

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

Remove these objects and use the fast-path.
