Vincent Poon resolved PHOENIX-3554.
-----------------------------------
    Resolution: Not A Bug

Opened PHOENIX-4373 which causes the issue described here, since it's not actually a problem with the IndexTool itself

> look here,the index data is wrong:
> \x02\x00\x0Ecar1\x002016-01-01 00:00:00\x001\x00\x00\x00\x00
> the right index data should be:
> \x02\x00\x0Ecar1\x002016-01-01 00:00:00\x001
> this is the reason i get any null value(the column not in index):
> 0: jdbc:phoenix:master> SELECT ORG_ID,CAP_DATE,CAR_NUM,ORG_NAME FROM C_PICRECORD WHERE  CAR_NUM='car1' AND CAP_DATE>='2016-01-01' AND CAP_DATE<='2016-05-02'  LIMIT 10;
> | ORG_ID  |       CAP_DATE       | CAR_NUM  | ORG_NAME  |
> | null    | 2016-01-01 00:00:00  | car1     |           |
> PS: I can get the right index data if change pk's datatype to bigint or upsert some string as pk such as 'abc'.
