하이브 INSERT OVERWRITE 오류 표시

Question

hiber-1.2.1과 hbase-0.98.19를 통합하는 예를 연구 중입니다. 나는

CREATE TABLE hbase_table_emp(id int, name string, role string) 
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" =  ":key,cf1:name,cf1:role") 
TBLPROPERTIES ("hbase.table.name" = "emp"); 

가 그럼 난 'hbase_table_emp'에 데이터를 가져 오기위한 'testemp'를 만든 명령을 사용하여 HBase를에서 테이블을 만들었습니다. 아래의 코드는 'testemp'테이블을 만드는 방법을 보여줍니다.

create table testemp(id int, name string, role string) row format delimited fields terminated by '\t'; 
load data local inpath '/home/hduser/sample.txt' into table testemp; 
select * from testemp; 

지금까지 모든 것이 잘 작동합니다. 내가 명령 insert overwrite table hbase_table_emp select * from testemp;

을 실행할 때 나는 다음과 같은 오류가 발생합니다 : -

PS : 나는 hbase.jar, zookeeper.jar이 있고 CLASSPATH에 포함 guava.jar.

미리 감사드립니다.

Answer 1

Hive HBase 통합의 경우 hbase 테이블에 데이터를 삽입하려면 TBLPROPERTIES에 hbase.mapred.output.outputtable도 지정해야합니다.

The hbase.mapred.output.outputtable property is optional; it's needed if you plan to insert data to the table (the property is used by hbase.mapreduce.TableOutputFormat)

Hive HBase Integration

그래서 테이블에 대해 다음과 같은 실행해야합니다 :

ALTER TABLE table_name SET TBLPROPERTIES ("hbase.mapred.output.outputtable" = "emp");
