Impala | KUDU Show PARTITION BY HASH. Where my row are?

Question

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?
