[jira] [Updated] (KUDU-1675) Obsolete approach for verifying
Impala-Kudu
[ https://issues.apache.org/jira/browse/KUDU-1675?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Suzanne McIntosh updated KUDU-1675:
-----------------------------------
Environment: VMWare VM running Centos 6.6 and Kudu 1.0 (0.10).
Description:
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 (here: http://kudu.apache.org/docs/kudu_impala_integration.html) 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' )
