------------------------------------
Summary: Building async local index by IndexTool generate wrong
data
Key: PHOENIX-3555
URL: https://issues.apache.org/jira/browse/PHOENIX-3555
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.8.0
Environment: phoenix4.8.0
Reporter: chenzhiming
1.a salt table which pk is varchar
CREATE TABLE C_PICRECORD (
ID VARCHAR NOT NULL PRIMARY KEY,
"info".CAR_NUM VARCHAR(18) NULL,
"info".CAP_DATE VARCHAR NULL,
"info".ORG_ID BIGINT NULL,
"info".ORG_NAME VARCHAR(255) NULL
) SALT_BUCKETS=3;
2.upsert into the table
UPSERT INTO C_PICRECORD(ID,CAR_NUM,CAP_DATE,ORG_ID,ORG_NAME)
VALUES('1','car1','2016-01-01 00:00:00',11,'orgname1');
3.create async local index
CREATE LOCAL INDEX C_PICRECORD_IDX_1 on
C_PICRECORD("info".CAR_NUM,"info".CAP_DATE) ASYNC;
4.use IndexTool to build index
hbase org.apache.phoenix.mapreduce.index.IndexTool --data-table C_PICRECORD
--index-table C_PICRECORD_IDX_1 --output-path /tmp/C_PICRECORD_IDX_1
5.enter into "hbase shell" and scan salt table
------------------------------------------------------------------------
hbase(main):102:0> scan 'C_PICRECORD'
ROW COLUMN+CELL
\x02\x00\x0Ecar1\x002016-01-01 00:00:00\x001\x0 column=L#0:_0,
timestamp=1483108992853, value=x
0\x00\x00\x00
\x021 column=info:CAP_DATE,
timestamp=1483021375797, value=2016-01-01 00:00:00
\x021 column=info:CAR_NUM,
timestamp=1483021375797, value=car1
\x021 column=info:ORG_ID,
timestamp=1483021375797, value=\x80\x00\x00\x00\x00\x00\x00\x0B
\x021 column=info:ORG_NAME,
timestamp=1483021375797, value=orgname1
\x021 column=info:_0,
timestamp=1483021375797, value=x
--------------------------------------------------------------------------
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'.
