I want to test CREATE TABLE with PARTITION BY HASH in KUDU
This is my CREATE clause.
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'
)
Some inserts...
insert into customers values ('madrid', 'pili', 8);
insert into customers values ('barcelona', 'silvia', 8);
insert into customers values ('galicia', 'susi', 8);
Avoiding issues...
COMPUTE STATS customers;
Query: COMPUTE STATS customers
+-----------------------------------------+
| summary |
+-----------------------------------------+
| Updated 1 partition(s) and 3 column(s). |
+-----------------------------------------+
And then...
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
Where my rows are? What means the "-1"?
There is any way to see if row distribution is workings properly?
