--------------------------------------
Summary: Obsolete approach for verifying Impala-Kudu
Key: KUDU-1675
URL: https://issues.apache.org/jira/browse/KUDU-1675
Project: Kudu
Issue Type: Bug
Components: documentation
Affects Versions: 0.10.0
Reporter: Suzanne McIntosh
The following select statement is no longer a valid way to test that
Impala-Kudu was successfully installed:
select if(version() like '%KUDU%', "all set to go!", "check your configs") as s;
'KUDU' is no longer embedded in the result returned by version():
[localhost.localdomain:21000] > version;
Shell version: Impala Shell v2.8.0-cdh5-INTERNAL () built on Fri Sep 16
00:09:21 PDT 2016
Server version: impalad version 2.8.0-cdh5-INTERNAL RELEASE (build )
Instead, the documentation should suggest an alternative approach to verify
that Impala-Kudu is functioning and integrated with Kudu. For example, verify
by creating a table as follows:
[localhost.localdomain:21000] > CREATE TABLE my_first_table ( id BIGINT, name
STRING ) DISTRIBUTE BY HASH INTO 16 BUCKETS TBLPROPERTIES( 'storage_handler' =
'com.cloudera.kudu.hive.KuduStorageHandler', 'kudu.table_name' =
'my_first_table', 'kudu.master_addresses' = '127.0.0.1:7051',
'kudu.key_columns' = 'id' );
Query: create TABLE my_first_table ( id BIGINT, name STRING ) DISTRIBUTE BY
HASH INTO 16 BUCKETS TBLPROPERTIES( 'storage_handler' =
'com.cloudera.kudu.hive.KuduStorageHandler', 'kudu.table_name' =
'my_first_table', 'kudu.master_addresses' = '127.0.0.1:7051',
'kudu.key_columns' = 'id' )
