Kylin Soong commented on PHOENIX-1577:
--------------------------------------

Timestamp's nanos filed should less or equal 999999999, and large or equal 0. 
But in some occasion PhoenixPreparedStatement try to set a value large than 
999999999, I have done a quick debug, the code
     pstmt.setTimestamp(2, timestramp, cal);
execute logic like
---
long millis = cal.getTimeInMillis();
int nanos = x.getNanos();
Timestamp ts = new Timestamp(millis);
ts.setNanos(ts.getNanos() + nanos);
---

Why org.apache.phoenix.util.DateUtil getTimestamp()  try to plus the  nanos?

> java.lang.IllegalArgumentException: nanos > 999999999 or < 0 while use 
> Calendar

> I use the link [1] code, there always nanos > 999999999 or < 0 error throw.
> If execute insert, the error looks like:
> ~~~
> Exception in thread "main" java.lang.IllegalArgumentException: nanos > 
> 999999999 or < 0
>       at java.sql.Timestamp.setNanos(Timestamp.java:386)

>       at 
> org.apache.phoenix.jdbc.PhoenixPreparedStatement.setTimestamp(PhoenixPreparedStatement.java:489)

> and select the error looks
> ~~~
> xception in thread "main" java.lang.IllegalArgumentException: nanos > 
> 999999999 or < 0
