Hive 分析数据过程

本贴最后更新于 1912 天前,其中的信息可能已经时过境迁

当 ClouderaManager 平台搭建好之后,如何分析数据。
以下是一个使用 Hive 来处理的过程。以供参考

登录根用户

评估分析模型:

在 hive 终端:

CREATE DATABASE IF NOT EXISTS transformdb;

建立维度表

CREATE TABLE IF NOT EXISTS transformdb.dimperson(
personkey BIGINT,
firstname STRING,
lastname    STRING
)
CLUSTERED BY (firstname,lastname,personkey) INTO 1 BUCKETS
STORED AS orc
TBLPROPERTIES('transactional'='true','orc.compress'='ZLIB','orc.create.index'='true');

建立 transformdb fct 事实表

CREATE TABLE IF NOT EXISTS transformdb.fctpersonaccount(
personaccountkey BIGINT,
personkey   BIGINT,
accountkey  BIGINT,
balance DECIMAL(18,9)
)
CLUSTERED BY (personkey,accountkey) INTO 1 BUCKETS
STORED AS orc
TBLPROPERTIES ('transactional'='true','orc.compress'='ZLIB','orc.create.index'='true');

建立新数据库:

CREATE DATABASE IF NOT EXISTS reportdb;
CREATE DATABASE IF NOT EXISTS organisedb;

创建表 account 维度表

CREATE TABLE IF NOT EXISTS transformdb.dimaccount(
accountkey BIGINT,
accountnumber INT
)
CLUSTERED BY (accountnumber,accountkey) INTO 1 BUCKETS

STORED AS orc
TBLPROPERTIES('transactional'='true','orc.compress'='ZLIB','orc.create.index'='true');


CREATE TABLE IF NOT EXISTS organisedb.dimaccount LIKE transformdb.dimaccount;

创建 organisedb fct 事实表

CREATE TABLE IF NOT EXISTS organisedb.fctpersonaccount(
personaccountkey BIGINT,
personkey BIGINT,
accountkey BIGINT,
balance  DECIMAL(18,9)
)
CLUSTERED BY (personkey,accountkey) INTO 1 BUCKETS
STORED AS orc
TBLPROPERTIES ('transactional'='true','orc.compress'='ZLIB','orc.create.index'='true');

创建表 organisedb.dimperson

CREATE TABLE IF NOT EXISTS organisedb.dimperson(
personkey BIGINT,
firstname STRING,
lastname    STRING
)
CLUSTERED BY (firstname,lastname,personkey) INTO 1 BUCKETS
STORED AS orc
TBLPROPERTIES ('transactional'='true','orc.compress'='ZLIB','orc.create.index'='true');

创建表 reportdb.report001

CREATE TABLE IF NOT EXISTS reportdb.report001(
firstname STRING,
lastname    STRING,
accountnumber INT,
balance DECIMAL(18,9)
)
CLUSTERED BY (firstname,lastname) INTO 1 BUCKETS
STORED AS orc
TBLPROPERTIES ('transactional'='true','orc.compress'='ZLIB','orc.create.index'='true');

建立评估模型

INSERT INTO TABLE reportdb.report001
SELECT
    dimperson.firstname,dimperson.lastname,
    dimaccount.accountnumber,
    fctpersonaccount.balance
FROM
    organisedb.fctpersonaccount
JOIN
    organisedb.dimperson
ON  
    fctpersonaccount.personkey =dimperson.personkey
JOIN
    organisedb.dimaccount
ON
    fctpersonaccount.accountkey = dimaccount.accountkey

检索数据库:

创建数据库:

CREATE DATABASE IF NOT EXISTS retrievedb;

将示例数据拷贝到 master 机器硬盘

scp -r 下载/00rawdata/  root@10.23.0.136:/tmp

建立 hdfs 文件夹

hadoop fs -mkdir /user/retrieve/ 

从 master 硬盘拷贝文件到 hdfs 文件系统

hadoop fs -put /tmp/00rawdata/ /user/retrieve

将文件置为可读可写可执行

hadoop fs -chmod 777 /user/retrieve/00rawdata/*.* 

创建各数据文件表,并加载数据

rawfirstname
CREATE TABLE IF NOT EXISTS retrievedb.rawfirstname (
  firstnameid    string,
  firstname      string,
  sex            string

)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';
LOAD DATA LOCAL INPATH 'file:///tmp/00rawdata/rawaccount.csv' OVERWRITE INTO TABLE retrievedb.rawaccount;

评估数据库:

创建评估数据库

CREATE DATABASE IF NOT EXISTS assessdb;

创建 firstname001 临时表 存储去除标题的数据

CREATE TABLE IF NOT EXISTS assessdb.firstname001 (

)
CLUSTERED BY (firstnameid) INTO 1 BUCKETS
STORED AS orc
TBLPROPERTIES('transactional' = 'true','orc.compress'='ZLIB','orc.create.index'='true');

清除表中数据

TRUNCATE TABLE assessdb.firstname001;

清除表中标题

INSERT INTO TABLE assessdb.firstname001
SELECT firstnameid, firstname, sex
FROM retrievedb.rawfirstname
WHERE firstnameid <> '"id"';

建立临时表 firstname002 存储删除空格的数据

SELECT firstnameid, rtrim(ltrim(firstname)), rtrim(ltrim(sex))
FROM assessdb.firstname001;

建立 firstname003 转换 firstname 中的数据类型

查询时遇到了 Execution Error, return code 3 from org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask
这是一个坑.
set hive.auto.convert.join=false
是mapjoin的问题.优化mapjoin的时候,触发了内存不足的阀值,但是内存可能够用
