我试图在现有的C *表上运行Hive查询。DSE中奇怪的dse配置单元集成4.7
这里是我的C *表定义:
CREATE EXTERNAL TABLE c_site_users(
user_id string, user_test_uuid binary, user_name string)
STORED BY 'org.apache.hadoop.hive.cassandra.cql3.CqlStorageHandler'
WITH SERDEPROPERTIES("cassandra.ks.name" = "mydata",
"cassandra.cf.name" = "site_users",
"cql3.partition.key" = "user_id",
"cassandra.cql3.type" = "text, uuid, text"
);
我插入的数据转换成C *表使用cqlsh:
cqlsh:appdata> select * from site_users;
user_id | user_name | user_test_uuid
---------+-----------+--------------------------------------
user2 | Ivan | 51569760-10e6-11e5-af86-23fdaf275fb9
user1 | Sergey | 51542660-10e6-11e5-af86-23fdaf275fb9
user3 | Johan | 5157a8d0-10e6-11e5-af86-23fdaf275fb9
(3 rows)
是我的外部蜂巢表定义
drop table IF EXISTS mydata.site_users;
CREATE TABLE IF NOT EXISTS appdata.site_users (
user_id text,
user_test_uuid uuid, --for testing purposes, if we can use it in queries, there could be some serde problems?
user_name text,
PRIMARY KEY (user_id)
);
这里
现在我尝试运行相同的查询使用dse配置单元
[email protected]:~$ dse hive
Logging initialized using configuration in file:/etc/dse/hive/hive-log4j.properties
hive> select * from c_site_users;
OK
Failed with exception java.io.IOException:java.io.IOException: com.datastax.driver.core.exceptions.UnavailableException: Not enough replica available for query at consistency LOCAL_ONE (1 required but only 0 alive)
Time taken: 13.297 seconds
太奇怪了! C *表是好的,数据在那里,我可以查询它,但dse配置单元抱怨。我做错了什么?
