Description

Timestamp values are reading additional one byte if nano-sec part is zero, breaking following columns.

>create table timestamp_1 (t timestamp, key string, value string);
>insert overwrite table timestamp_1 select cast('2011-01-01 01:01:01' as timestamp), key, value from src limit 5;

>select t,key,value from timestamp_1;
2011-01-01 01:01:01		238
2011-01-01 01:01:01		86

2011-01-01 01:01:01		27
2011-01-01 01:01:01		165

>select t,key,value from timestamp_1 distribute by t;
