>                 URL: https://issues.apache.org/jira/browse/HBASE-15233

> Today we have this:
> {code}
>   public static byte[] toBytes(long val) {
>     byte [] b = new byte[8];
>     for (int i = 7; i > 0; i--) {
>       b[i] = (byte) val;
>       val >>>= 8;
>     }
>     b[0] = (byte) val;
>     return b;
>   }
> {code}
> might be nice to also have this:
> {code}
>   public static byte[] toBytes(long val, byte[] reuse) {
>     for (int i = 7; i > 0; i--) {
>       reuse[i] = (byte) val;
>       val >>>= 8;
>     }
>     reuse[0] = (byte) val;
>     return reuse;
>   }
> {code}
> Same for all the other Bytes.toBytes() methods.
