Phoenix-选择HBase表-0行

编程问答 2022-08-11

问题描述

我想使用Phoenix服务从hbase中选择行。我收到以下错误： 错误：错误1036（42J04）：如果父级的最后一个PK列的长度可变，则无法修改VIEW的主键。 columnName = tbl1.pk（状态= 42J04，代码= 1036）

我使用了以下来源的参考： https://godbolt.org/ https://phoenix.apache.org/faq.html#How_I_map_Phoenix_table_to_an_existing_HBase_table

我做了什么：

hbase> describe 'tbl1'

tbl1，{TABLE_ATTRIBUTES => {coprocessor $ 1 =>'| org.apache.phoenix.coprocessor.ScanRegionObserver | 805306366 |'，cop rocessor $ 2 =>'| org.apache.phoenix.coprocessor.UngroupedAggregateRegionObserver | 805306366 |'，coprocessor $ 3 =>'| org.apac he.phoenix.coprocessor.GroupedAggregateRegionObserver | 805306366 |'，协处理器$ 4 =>'| org.apache.phoenix.coprocessor.Ser verCachingEndpointImpl | 805306366 |'}

hbase> scan 'tbl1',{LIMIT=>2}

phoenix>create table "tbl1" ( "pk" VARCHAR PRIMARY KEY,"C"."s" VARCHAR,"C"."t" VARCHAR);
phoenix>create view "CanonicalId_view_s" ( "pk" VARCHAR PRIMARY KEY,"C"."t" VARCHAR) as select * from "CanonicalId";

我收到以下错误：
