not able to create table in kudu using impala-shell - impala

Question

I was doing R&D on hadoop, hive, impala, and kudu. Installed HADOOP, HIVE, IMPALA, and KUDU servers.
I have configured --kudu_master_hosts=: in /etc/default -> impala file. i.e like below:
IMPALA_SERVER_ARGS=" \
-log_dir=${IMPALA_LOG_DIR} \
-catalog_service_host=${IMPALA_CATALOG_SERVICE_HOST} \
-state_store_port=${IMPALA_STATE_STORE_PORT} \
-use_statestore \
-state_store_host=${IMPALA_STATE_STORE_HOST} \
-be_port=${IMPALA_BACKEND_PORT}\
--kudu_master_hosts=<HOST_NAME>:<PORT>"
==============
Aftert that re-started the servers.
Then using Kudu JAVA client, i was able to create table in kudu and able to insert some records.
Then mapped the same table in impala by doing this:
CREATE EXTERNAL TABLE my_mapping_table
STORED AS KUDU
TBLPROPERTIES (
'kudu.table_name' = 'testT1'
);
successfully able to access the kudu table in impala and able to see all the records.
Now i was trying to create a table in KUDU using impala-shell.
[<HOST_NAME>:21000] > CREATE TABLE my_first_table
> (
> id BIGINT,
> name STRING,
> PRIMARY KEY(id)
> )
> STORED AS KUDU;
But this is giving a error i.e :
ERROR: ImpalaRuntimeException: Error creating Kudu table 'impala::default.my_first_table'
CAUSED BY: NonRecoverableException: Not enough live tablet servers to create a table with the requested replication factor 3. 1 tablet servers are alive.
Can any one explain me what is happening or what is the solution for this error.
Read through KUDU documentation but not getting any ideas.

Answer 1

This query will help to create table i.e
CREATE TABLE emp
(
uname STRING,
age INTEGER,
PRIMARY KEY(uname)
)
STORED AS KUDU
TBLPROPERTIES (
'kudu.num_tablet_replicas' = '1'
);
This query will work only if, --kudu_master_hosts=: is set in /etc/default impala file.
Else u have to give kudu_master_hosts in table properties. i.e
TBLPROPERTIES (
'kudu.num_tablet_replicas' = '1',
--kudu_master_hosts=<HOST_NAME>:<PORT>
);
