Sql 配置单元：无法从配置单元表中的文件插入数组和映射

这是我所拥有的表的模式

CREATE DATABASE IF NOT EXISTS mydb;
USE mydb;

CREATE TABLE IF NOT EXISTS mytab (

idcol   string,
arrcol  array<string>,
mapcol  map<string,string>
)
PARTITIONED BY (data_date string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '|'
STORED AS TEXTFILE;

看起来加载对数据进行了一些转换。它保留了字符串值，但是数组和映射存在一些问题

如何正确插入阵列和映射

我还尝试了以下内容作为输入

123 |数组（“a”、“b”）{“1”：“a”、“2”：“b”}

加载成功，但当我查询数据时，我得到了

root@0d2b0044b4c1:/opt# hive -e "use mydb;select * from mytab;"

更新

非常感谢pedram bashiri的回答。我创建了外部表并能够填充它。但是，所有内容都以字符串形式填充

hive> drop table if exists extab;
OK
Time taken: 0.01 seconds
hive> create external table extab(idcol string,arrcol array<string>,mapcol map<string,string>, data_date string)
    >   row format serde 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
    > with serdeproperties (
    >   "separatorChar" = "|",
    >   "quoteChar"     = "\"",
    >   "escapeChar"    = "\\"
    >   )
    >   stored as textfile
    > location '/tmp/serdes/';
OK
Time taken: 0.078 seconds
hive> desc extab;
OK
idcol                   string                  from deserializer
arrcol                  string                  from deserializer
mapcol                  string                  from deserializer
data_date               string                  from deserializer
Time taken: 0.059 seconds, Fetched: 4 row(s)
hive> select * from extab;
OK
123 ["a","b"]   {"1":"a","2":"b"}   2019
Time taken: 0.153 seconds, Fetched: 1 row(s)
hive>

我也试过了

create external table extab(idcol string,arrcol array<string>,mapcol map<string,string>, data_date string)
  row format serde 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
with serdeproperties (
  "separatorChar" = "|"
  )
  stored as textfile
location '/tmp/serdes/';

创建外部表extab（idcol字符串、arrcol数组、mapcol映射、数据\日期字符串）
行格式serde'org.apache.hadoop.hive.serde2.OpenCSVSerde'
具有serdeproperty(
“separatorChar”=“|”
)
存储为文本文件
位置“/tmp/serdes/”；

但是，所有内容都存储为字符串，因此现在我在尝试插入时会发现类型不匹配。

用于根据psv文件创建一个外部表，并将其称为mytab\u external。指定SerdeProperty，如

with serdeproperties (
"separatorChar" = "|",
"quoteChar"     = """,
"escapeChar"    = "\\"
)

然后简单地做

INSERT INTO mytab
SELECT * FROM mytab_external;

---

所以经过大量挖掘，我找到了答案

CREATE TABLE IF NOT EXISTS mytab (

idcol   string,
arrcol  array<string>,
mapcol  map<string,string>
)
PARTITIONED BY (data_date string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '|'
COLLECTION ITEMS TERMINATED BY ','
MAP KEYS TERMINATED BY '='
STORED AS TEXTFILE;

---

这正是我需要的

非常感谢这些建议。请看我的更新。外部表中的所有内容都以字符串形式填充，因此由于类型不匹配，无法插入到表中

INSERT INTO mytab
SELECT * FROM mytab_external;

CREATE TABLE IF NOT EXISTS mytab (

idcol   string,
arrcol  array<string>,
mapcol  map<string,string>
)
PARTITIONED BY (data_date string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '|'
COLLECTION ITEMS TERMINATED BY ','
MAP KEYS TERMINATED BY '='
STORED AS TEXTFILE;
