kuduSink.md

1.格式：

CREATE TABLE tableName(
    colName colType,
    ...
    colNameX colType
 )WITH(
    type ='kudu',
    kuduMasters ='ip1,ip2,ip3',
    tableName ='impala::default.test',
    writeMode='upsert',
    workerCount='1',
    defaultOperationTimeoutMs='600000',
    defaultSocketReadTimeoutMs='6000000',
    parallelism ='parllNum'
 );

2.支持版本

kudu 1.9.0+cdh6.2.0

3.表结构定义

参数名称	含义
tableName	在 sql 中使用的名称;即注册到flink-table-env上的名称
colName	列名称，redis中存储为 表名:主键名:主键值:列名]
colType	列类型 colType支持的类型

4.参数：

参数名称	含义	是否必填	默认值
type	表名 输出表类型[mysq|hbase|elasticsearch|redis|kudu]	是
kuduMasters	kudu master节点的地址;格式ip[ip，ip2]	是
tableName	kudu 的表名称	是
writeMode	写入kudu的模式 insert|update|upsert	否	upsert
workerCount	工作线程数	否
defaultOperationTimeoutMs	操作超时时间	否
defaultSocketReadTimeoutMs	socket读取超时时间	否
parallelism	并行度设置	否	1
principal	kerberos用于登录的principal	否
keytab	keytab文件的路径	否
krb5conf	conf文件路径	否
Kerberos三个参数全部设置则开启Kerberos认证，如果缺少任何一个则会提示缺少参数错误。
如果全部未设置则不开启Kerberos连接Kudu集群。

    kuduMasters ='cdh03.cdhsite:7051',
    tableName ='myresult',
    writeMode='insert',
    parallelism ='1'
 );

CREATE TABLE sideTable(
    c string,
    d string,
    PRIMARY KEY(c) ,

insert         
into
    MyResult
    select
        MyTable.a,
        MyTable.b,
        s.c,
        s.d                                
    from
        MyTable                                    
    join
        sideTable s

    where
        MyTable.a='2'                                                              
        and s.d='2'

6.数据示例

输入数据

{"channel":"daishuyun","name":"roc","pv":"10","a":"2","b":"2"}

结果数据

{"a":"2","b":"2","c":"3","d":"4"}

7.kerberos示例

create table dwd (
    name varchar,
    id int
) WITH (
    type='kudu',
    kuduMasters='host1',
    tableName='foo',
    writeMode='insert',
    parallelism ='1',
    keytab='foo/foobar.keytab',
    krb5conf='bar/krb5.conf',
    principal='kudu/host1@DTSTACK.COM'
);
