七.使用copy加載數據

1. 指定的目錄master節點必須可以訪問到

copy region from '/tmp/data/region.tbl'
with delimiter '|';
--log errors into errtable segment reject limit 10 rows;

八.hawq load工具程序加載數據

1. 在gpfdist節點上修改 /home/gpadmin/.bash_profile

在文件末尾增加如下內容： 

     source /usr/local/hawq/greenplum_path.sh

2.安裝依賴

sudo yum install -y libevent libyaml apr

3. 創建表格

create table audit(cmd varchar(10), t timestamp);

4. 啓動gpfdist文件服務器

gpfdist -p 8081 -d /tmp/data -l ~/log &

5.新增配置文件load.yaml，內容如下：

---
VERSION: 1.0.0.1
DATABASE: tpc_h
USER: gpadmin
HOST: master1
PORT: 5432
GPLOAD:
   INPUT:
    - SOURCE:
         LOCAL_HOSTNAME:
           - worker1
         PORT: 8081
         FILE: 
           - region.tbl
    - COLUMNS:
           - r_regionkey: integer
           - r_name: text
           - r_comment: text
           - r_extra: text
    - FORMAT: text
    - DELIMITER: '|'
    - ERROR_LIMIT: 25
    - ERROR_TABLE: public.errortable
   OUTPUT:
    - TABLE: public.region
    - MODE: INSERT
   SQL:
    - BEFORE: "INSERT INTO audit VALUES('start', current_timestamp)"
    - AFTER: "INSERT INTO audit VALUES('end', current_timestamp)"

4. 執行hawq load命令

hawq load -f load.yaml

Apache Hawq功能測試腳本

九. PXF插件加載HDFS數據

1.創建外部表

drop external table if exists pxf_hdfs_textsimple;
create external table pxf_hdfs_textsimple(location text, month text, num_orders int, total_sales float8)
            location ('pxf://mycluster/hawq_fs/pxf_data/pxf_hdfs_simple.txt?profile=hdfstextsimple')
          format 'text' (delimiter=e',');

//namenode單點時：master1.bigdata是指namenode節點，端口是pxf的端口地址

create external table pxf_hdfs_textsimple(location text, month text, num_orders int, total_sales float8)
            location ('pxf://master1.bigdata:51200/hawq_fs/pxf_data/pxf_hdfs_simple.txt?profile=hdfstextsimple')
          format 'text' (delimiter=e',');

自定義空值：

drop external table if exists h.pxf_inventory;
create external table h.pxf_inventory
(
    inv_date_sk               integer,
    inv_item_sk               integer,
    inv_warehouse_sk          integer,
    inv_quantity_on_hand      integer,
    inv_null                  varchar(10)
)location ('pxf://master1.bigdata:51200/tpcdsdata/30T/inventory/data-m-*?profile=hdfstextsimple')
format 'TEXT' (DELIMITER '|' NULL '');

2. 創建pxf_hdfs_simple.txt文件，內容：

echo 'Prague,Jan,101,4875.33
Rome,Mar,87,1557.39
Bangalore,May,317,8936.99
Beijing,Jul,411,11600.67' > /tmp/pxf_hdfs_simple.txt

3.文件上傳至hdfs

hdfs dfs -put /tmp/pxf_hdfs_simple.txt  /hawq_fs/pxf_data/

hdfs dfs -cat /hawq_fs/pxf_data/pxf_hdfs_simple.txt

Apache Hawq功能測試腳本

select * from pxf_hdfs_textsimple;

1.創建hawq數據表

drop table if exists salesinfo;
create table salesinfo(location text, month text, num_orders int, total_sales float8)
with(appendonly=true,orientation=parquet,compresstype=snappy)
distributed randomly;

1. hive中創建表sales_info

/usr/hdp/current/hive-client/bin
./hive
drop table if exists sales_info;
create table sales_info (location string, month string,
        number_of_orders int, total_sales double)
        row format delimited fields terminated by ','
        stored as textfile;
Prague,Jan,101,4875.33
Rome,Mar,87,1557.39
Bangalore,May,317,8936.99
Beijing,Jul,411,11600.67
San Francisco,Sept,156,6846.34
Paris,Nov,159,7134.56
San Francisco,Jan,113,5397.89
Prague,Dec,333,9894.77
Bangalore,Jul,271,8320.55
Beijing,Dec,100,4248.41

2. load 數據到hive數據表中

load data local inpath '/tmp/pxf_hive_datafile.txt'
        into table sales_info;

Apache Hawq功能測試腳本

方法一：創建外部表

psql

1.創建外部表方式

drop table if exists salesinfo_hiveprofile;
create external table salesinfo_hiveprofile(location text, month text, num_orders int, total_sales float8)
            location ('pxf://mycluster/default.sales_info?profile=hive')
          format 'custom' (formatter='pxfwritable_import');

Apache Hawq功能測試腳本

2. 導入數據

insert into salesinfo select * from salesinfo_hiveprofile;

Apache Hawq功能測試腳本

方法二：讀取hive Hcatalog 元數據服務

這種方式需要修改pxf-profiles.xml中關於Hive的內容，增加outputformat對象

HiveText：

<outputformat>org.apache.hawq.pxf.service.io.Text</outputformat>

HiveORC：

<outputformat>org.apache.hawq.pxf.service.io.GPDBWritable</outputformat>

HiveRC：

<outputformat>org.apache.hawq.pxf.service.io.Text</outputformat>

Hive

<outputformat>org.apache.hawq.pxf.service.io.GPDBWritable</outputformat>

格式：

SELECT * FROM hcatalog.hive-db-name.hive-table-name;

　如：

 SELECT * FROM hcatalog.default.sales_info;

Apache Hawq功能測試腳本
導入數據：

insert into salesinfo SELECT * FROM hcatalog.default.sales_info;

Apache Hawq功能測試腳本

十一. PXF插件加載HBASE數據

--方式1，直接引用列族和Qualifier

1. 創建外部表

drop EXTERNAL  table if exists hbase_sales;
create external table hbase_sales(
recordkey bytea,
"cf1:saleid" varchar,
"cf8:comments" varchar)
location ('pxf://mycluster/sales?profile=hbase')
format 'custom'(formatter='pxfwritable_import')
encoding 'utf8';

2. 使用HBase Shell創建HBase數據表，並寫入數據

cd /usr/hdp/current/hbase-client/bin
./hbase shell

創建表格

create 'sales', {NAME=>'cf1',VERSION=>2},{NAME=>'cf8',VERSION=>2}
#create 'pxf_hbase_region', {NAME=>'cf1',VERSION=>2}

Apache Hawq功能測試腳本
寫入數據

put 'sales','rk001','cf1:saleid', 's001'
put 'sales','rk001','cf8:comments', 'comments1'
select * from hbase_sales;

Apache Hawq功能測試腳本

--方式2，在HBase中創建pxflookup表

create 'pxflookup', {NAME=>'mapping',VERSION=>2}

put 'pxflookup', 'sales', 'mapping:id', 'cf1:saleid'
put 'pxflookup', 'sales', 'mapping:cmts', 'cf8:comments'

drop EXTERNAL  table if exists pxf_hbase_sales ;
CREATE EXTERNAL TABLE pxf_hbase_sales (
  recordkey bytea,
  id varchar,
  cmts varchar
)location ('pxf://mycluster/sales?profile=hbase')
format 'custom'(formatter='pxfwritable_import')
encoding 'utf8';

select * from pxf_hbase_sales;

十二. PXF訪問Jdbc（mysql)

grant all privileges on *.* to "pxf"@"%" identified by 'test';
 mysql> use test;
 mysql> create table myclass(
          id int(4) not null primary key,
          name varchar(20) not null,
          gender int(4) not null default '0',
          degree double(16,2));
insert into myclass values(1,"tom",1,90);
insert into myclass values(2,'john',0,94);
insert into myclass values(3,'simon',1,79);

/etc/pxf/conf/pxf-public.classpath添加/usr/lib/pxf/mysql-connector-java-*.jar

psql：

gpadmin=#
drop external table if exists jdbc_myclass;
 CREATE EXTERNAL TABLE jdbc_myclass(id integer,
      name text,
      gender integer,
      degree float8)
      LOCATION ('pxf://localhost:51200/test.myclass'
              '?PROFILE=JDBC'
              '&JDBC_DRIVER=com.mysql.jdbc.Driver'
              '&DB_URL=jdbc:mysql://10.110.22.191:3306/test&USER=pxf&PASS=test'
              )

      LOCATION ('pxf://localhost:51200/test.sales_info'
              '?PROFILE=JDBC'
              '&JDBC_DRIVER=com.mysql.jdbc.Driver'
              '&DB_URL=jdbc:mysql://10.110.22.191:3306/test&USER=pxf&PASS=test'
              )
     FORMAT 'CUSTOM' (Formatter='pxfwritable_import');

CREATE EXTERNAL TABLE sales(id integer,
             cdate date,

十四. PXF插件寫數據到HDFS

1.創建可寫外部表

create writable external table pxf_hdfs_writabletbl_1(location text, month text, num_orders int, total_sales float8)
            location ('pxf://mycluster/hawq_fs/pxf_data/pxfwritable_hdfs_textsimple1?profile=hdfstextsimple')
          format 'text' (delimiter=e',');

2.寫入數據

insert into pxf_hdfs_writabletbl_1 values ( 'frankfurt', 'mar', 777, 3956.98 );
insert into pxf_hdfs_writabletbl_1 values ( 'cleveland', 'oct', 3812, 96645.37 );
