问题描述
我想在 KUDU 中使用 PARTITION BY HASH 测试 CREATE TABLE
这是我的 CREATE 子句。
CREATE TABLE customers (
state STRING,name STRING,purchase_count int,PRIMARY KEY (state,name)
)
PARTITION BY HASH (state) PARTITIONS 2
STORED AS KUDU
TBLPROPERTIES (
'kudu.master_addresses' = '127.0.0.1','kudu.num_tablet_replicas' = '1'
)
一些插入...
insert into customers values ('madrid','pili',8);
insert into customers values ('barcelona','silvia',8);
insert into customers values ('galicia','susi',8);
避免问题...
COmpuTE STATS customers;
Query: COmpuTE STATS customers
+-----------------------------------------+
| summary |
+-----------------------------------------+
| Updated 1 partition(s) and 3 column(s). |
+-----------------------------------------+
然后……
show partitions customers;
Query: show partitions customers
+--------+-----------+----------+----------------+------------+
| # Rows | Start Key | Stop Key | leader Replica | # Replicas |
+--------+-----------+----------+----------------+------------+
| -1 | | 00000001 | hidra:7050 | 1 |
| -1 | 00000001 | | hidra:7050 | 1 |
+--------+-----------+----------+----------------+------------+
Fetched 2 row(s) in 2.31s
我的行在哪里? “-1”是什么意思?
有什么方法可以查看行分布是否正常工作?
