文件内容如下:

filespace:fs_tpc_h
fsreplica:3
dfs_url::mycluster/hawq_fs/fs_tpc_h

2. 创建HDFS目录

$hdfs dfs -mkdir /hawq_fs
$hdfs dfs -chown gpadmin:gpadmin /hawq_fs
$hdfs dfs -ls /

七.使用copy加载数据

1. 指定的目录master节点必须可以访问到

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

八.hawq load工具程序加载数据

1. 在gpfdist节点上修改 /home/gpadmin/.bash_profile

在文件末尾增加如下内容: source /usr/local/hawq/greenplum_path.sh

2.sudo yum install -y libevent libyaml apr

3. 创建表格

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

4. 启动gpfdist文件服务器

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

5.新增配置文件load.yaml,内容如下:

---
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. 执行hawq load命令

hawq load -f load.yaml

九. PXF插件加载HDFS数据

1.创建外部表

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单点时:master1.bigdata是指namenode节点,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‘,‘);

自定义空值:

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. 创建pxf_hdfs_simple.txt文件,内容:

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.文件上传至hdfs

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

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

十. PXF插件加载HIVE数据

1.创建hawq数据表

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中创建表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 数据到hive数据表中

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

技术分享图片

方法一:创建外部表

psql

1.创建外部表方式

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‘);

2. 导入数据

insert into salesinfo select * from salesinfo_hiveprofile;

方法二:读取hive Hcatalog 元数据服务

这种方式需要修改pxf-profiles.xml中关于Hive的内容,增加outputformat对象

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;

导入数据:

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

十一. PXF插件加载HBASE数据
--方式1,直接引用列族和Qualifier

  1. 创建外部表
    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创建HBase数据表,并写入数据
    cd /usr/hdp/current/hbase-client/bin
    ./hbase shell
    创建表格
    create ‘sales‘, {NAME=>‘cf1‘,VERSION=>2},{NAME=>‘cf8‘,VERSION=>2}
    #create ‘pxf_hbase_region‘, {NAME=>‘cf1‘,VERSION=>2}

写入数据
put ‘sales‘,‘rk001‘,‘cf1:saleid‘, ‘s001‘
put ‘sales‘,‘rk001‘,‘cf8:comments‘, ‘comments1‘

select * from hbase_sales;

--方式2,在HBase中创建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访问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

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‘
)
FORMAT ‘CUSTOM‘ (Formatter=‘pxfwritable_import‘);

select * from jdbc_myclass;

slaes_info:
create table sales_info (location varchar(200), month varchar(10),
number_of_orders int, total_sales double);

insert into sales_info values("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);

psql:
drop external table if exists jdbc_sales_info ;
CREATE EXTERNAL TABLE jdbc_sales_info (location varchar(200), month varchar(10),
number_of_orders integer, total_sales float8)
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,
amt float8,
grade text)
LOCATION (‘pxf://localhost:51200/sales‘
‘?PROFILE=JDBC‘
‘&JDBC_DRIVER=com.mysql.jdbc.Driver‘
‘&DB_URL=jdbc:mysql://192.168.200.6:3306/demodb&USER=root&PASS=root‘
‘&PARTITION_BY=cdate:date&RANGE=2008-01-01:2010-01-01&INTERVAL=1:year‘
)
FORMAT ‘CUSTOM‘ (Formatter=‘pxfwritable_import‘);

十三. gpfdist卸载数据

方法一: gpfdist 定义基于文件的可写外部表

  1. 定义可写外部表
    create writable external table unload_region
    (like region)
    location (‘gpfdist://10.110.17.104:8081/exp_region.tbl‘)
    format ‘text‘ (delimiter ‘,‘);

--只可写,不可读

  1. 导入数据
    insert into unload_region select * from region;

  2. 查看导出的数据文件exp_region.tbl
    cat exp_region.tbl

方法二 使用copy卸载数据
copy region
to ‘/home/gpadmin/region.out‘;

copy (select * from region where r_regionkey=1) 
to ‘/home/gpadmin/region.out‘;

十三. PXF插件写数据到HDFS

1.创建可写外部表

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.写入数据

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