openLooKeng配置Hbase连接器

openLooKeng给大家的直观感觉是包了一层Presto（特别是看了源码的工程后，自己曾经也有这样的想法），其实不是这样的（随着研究的深入，发现不是简单的包了下Presto，还是有很多自己的东西的，点个赞给openLooKeng。当然现在还是个小白，昨天很开心的发现了一个bug，自己修完后，发现12天前已经被fix了，哭～～），openLooKeng还是做了很多的改进的，比如多数据中心的概念，Hbase的connector，今天主要介绍下openLooKeng Hbase connector的简单配置，并和hive数据源做简单的笛卡尔积。

默认你已经熟悉了openLooKeng的安装，如果不熟悉请参看我的链接: 手动安装openLooKeng.
openLooKeng官网上现在能下载最新的版本是1.0.1，这个版本hbase connector 有很多bug，不能用，可以自己编译打包1.1.0版本，或者等后续1.1.0正式发布。这里我们自行编译打包1.1.0版本。下载源码请到openLooKeng源码. 虽然我更喜欢在github上，一是由于网速简直太慢，二是中国人嘛，当然支持咱们自己的东西啦。clone 下的源码直接

mvn install -DskipTests

就好。如果是下载下来的源码，编译时会遇到

通过修改pom，添加如下配置，skip掉 git-commit-id-plugin

...
<plugins>
            <!-- new added -->
            <plugin>
                <groupId>pl.project13.maven</groupId>
                <artifactId>git-commit-id-plugin</artifactId>
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>
...

然后进行编译：

解压openLooKeng安装包，catalog的配置 etc/catalog/hbase197.properties 具体参数配置可阅读官网，这里不多解释

[root@ocdp198 catalog]# cat hbase197.properties
connector.name=hbase-connector
hbase.zookeeper.quorum=10.1.235.197,10.1.235.198,10.1.235.199
hbase.zookeeper.property.clientPort=2181
hbase.zookeeper.znode.parent=/hbase-unsecure
hbase.metastore.type=hetuMetastore

使用openLooKeng元存储来存储HBase元数据 etc/hetu-metastore.properties 具体参数配置可阅读官网，这里不多解释。这里我们用mysql做存储，官网上介绍还可以用HDFS作为元数据存储（我未进行尝试）。

[root@ocdp198 etc]# cat hetu-metastore.properties
hetu.metastore.type=jdbc
hetu.metastore.db.url=jdbc:mysql://dp200:3306/hetum101236198
hetu.metastore.db.user=***
hetu.metastore.db.password=***

启动openLooKeng，并登录cli, hbase catalog已经加载

lk> show catalogs;
 Catalog
----------
 hbase197
 hive
 system
(3 rows)

对于HBase连接器支持两种建表形式：1. 创建表并直接链接到HBase数据源中已存在的表。2. 创建HBase数据源中不存在的新表。

openLooKeng 创建新表

lk> CREATE TABLE hbase197.default.member3 (
 ->     rowId       VARCHAR,
 ->     age1    INTEGER
 -> );
CREATE TABLE
lk> insert into hbase197.default.member3 values('11111',234567);
INSERT: 1 row

Query 20201209_060113_00009_wevd7, FINISHED, 1 node
Splits: 35 total, 35 done (100.00%)
0:01 [0 rows, 0B] [0 rows/s, 0B/s]

lk> select * from hbase197.default.member3;
 rowid |  age1
-------+--------
 11111 | 234567
(1 row)

Query 20201209_060119_00010_wevd7, FINISHED, 1 node
Splits: 17 total, 17 done (100.00%)
0:00 [1 rows, 11B] [4 rows/s, 48B/s]

Hbase中查看新表：

[ocdp@dp197 root]$ hbase shell
hbase(main):001:0>
hbase(main):002:0* list
TABLE
member
member1
member2
member3
4 row(s)
Took 0.5402 seconds
=> ["member", "member1", "member2", "member3"]
hbase(main):003:0> scan 'member3'
ROW                                                  COLUMN+CELL
 11111                                               column=family:age1, timestamp=1607493336908, value=234567
1 row(s)
Took 0.2353 seconds
hbase(main):004:0>

openLooKeng 关联Hbase已经存在的表
Hbase shell 创建表

hbase(main):009:0> create 'member7','info'
Created table member7
Took 1.3789 seconds
=> Hbase::Table - member7
hbase(main):010:0> put 'member7','12345678','info:age','27'
Took 0.0859 seconds
hbase(main):011:0> scan 'member7'
ROW                                                  COLUMN+CELL
 12345678                                            column=info:age, timestamp=1607493983862, value=27
1 row(s)
Took 0.0103 seconds
hbase(main):012:0>

openLooKeng关联映射已存在表

lk> CREATE TABLE hbase197.default.member7 (
 ->     rowId       VARCHAR,
 ->     age1    INTEGER
 -> )
 -> WITH (
 ->     column_mapping = 'age1:info:age',
 ->     row_id = 'rowId',
 ->     hbase_table_name = 'default:member7'
 -> );
CREATE TABLE
lk> select * from hbase197.default.member7;
  rowid   | age1
----------+------
 12345678 |   27
(1 row)

Query 20201209_061349_00025_wevd7, FINISHED, 1 node
Splits: 17 total, 17 done (100.00%)
0:00 [1 rows, 10B] [4 rows/s, 44B/s]

映射关系的格式为：‘column_name : family : qualifier’ 具体细节请参考官网

CREATE TABLE schemaName.tableName (
    rowId		VARCHAR,
    qualifier1	TINYINT,
    qualifier2	SMALLINT,
    qualifier3	INTEGER,
    qualifier4	BIGINT,
    qualifier5	DOUBLE,
    qualifier6	BOOLEAN,
    qualifier7	TIME,
    qualifier8	DATE,
    qualifier9	TIMESTAMP
)
WITH (
    column_mapping = 'qualifier1:f1:q1, qualifier2:f1:q2, 
    qualifier3:f2:q3, qualifier4:f2:q4, qualifier5:f2:q5, qualifier6:f3:q1, 
    qualifier7:f3:q2, qualifier8:f3:q3, qualifier9:f3:q4',
    row_id = 'rowId',
    hbase_table_name = 'hbaseNamespace:hbaseTable',
    external = false
);

最后做一个hbae和hive的笛卡尔积吧

lk> select * from hbase197.default.member7, hive.prestotest.score ;
  rowid   | age1 | sno |  cno  | degree
----------+------+-----+-------+--------
 12345678 |   27 | 105 | 3-105 |     88
 12345678 |   27 | 101 | 6-166 |     85
 12345678 |   27 | 103 | 3-105 |     92
 12345678 |   27 | 105 | 3-245 |     75
 12345678 |   27 | 107 | 6-166 |     79
 12345678 |   27 | 109 | 3-245 |     68
 12345678 |   27 | 109 | 3-105 |     76
 12345678 |   27 | 107 | 3-105 |     91
 12345678 |   27 | 108 | 3-105 |     78
 12345678 |   27 | 103 | 3-245 |     86
 12345678 |   27 | 101 | 3-105 |     64
 12345678 |   27 | 108 | 6-166 |     81
(12 rows)

Query 20201209_061624_00032_wevd7, FINISHED, 1 node
Splits: 46 total, 46 done (100.00%)
0:07 [25 rows, 14.7KB] [3 rows/s, 2.17KB/s]
