2、修改sql配置文件

cd /usr/local/service/flink-1.11.2/conf

vim sql-client-defaults.yaml

最终sql-client-default.yaml文件内容,修改的时候主要注意一下格式，把''[]'' 去掉（catalogs:[]  # empty list）

#==============================================================================
# Tables
#==============================================================================

# Define tables here such as sources, sinks, views, or temporal tables.

tables: [] # empty list
# A typical table source definition looks like:
# - name: ...
#   type: source-table
#   connector: ...
#   format: ...
#   schema: ...

# A typical view definition looks like:
# - name: ...
#   type: view
#   query: "SELECT ..."

# A typical temporal table definition looks like:
# - name: ...
#   type: temporal-table
#   history-table: ...
#   time-attribute: ...
#   primary-key: ...


#==============================================================================
# User-defined functions
#==============================================================================

# Define scalar, aggregate, or table functions here.

functions: [] # empty list
# A typical function definition looks like:
# - name: ...
#   from: class
#   class: ...
#   constructor: ...


#==============================================================================
# Catalogs
#==============================================================================

# Define catalogs here.

catalogs:  # empty list
# A typical catalog definition looks like:

#==============================================================================
# Modules
#==============================================================================

# Define modules here.

#modules: # note the following modules will be of the order they are specified
#  - name: core
#    type: core

#==============================================================================
# Execution properties
#==============================================================================

# Properties that change the fundamental execution behavior of a table program.

execution:
  # select the implementation responsible for planning table programs
  # possible values are 'blink' (used by default) or 'old'
  planner: blink
  # 'batch' or 'streaming' execution
  type: streaming
  # allow 'event-time' or only 'processing-time' in sources
  time-characteristic: event-time
  # interval in ms for emitting periodic watermarks
  periodic-watermarks-interval: 200
  # 'changelog', 'table' or 'tableau' presentation of results
  result-mode: table
  # maximum number of maintained rows in 'table' presentation of results
  max-table-result-rows: 1000000
  # parallelism of the program
  parallelism: 1
  # maximum parallelism
  max-parallelism: 128
  # minimum idle state retention in ms

  # maximum idle state retention in ms
  max-idle-state-retention: 0
  # current catalog ('default_catalog' by default)

  #current-database: default_database
  current-database: default
  # controls how table programs are restarted in case of a failures
  restart-strategy:
    # strategy type
    # possible values are "fixed-delay", "failure-rate", "none", or "fallback" (default)
    type: fallback

#==============================================================================
# Configuration options
#==============================================================================

# Configuration options for adjusting and tuning table programs.

# A full list of options and their default values can be found
# on the dedicated "Configuration" web page.

# A configuration can look like:
# configuration:
#   table.exec.spill-compression.enabled: true
#   table.exec.spill-compression.block-size: 128kb
#   table.optimizer.join-reorder-enabled: true

#==============================================================================
# Deployment properties
#==============================================================================

# Properties that describe the cluster to which table programs are submitted to.

deployment:
  # general cluster communication timeout in ms
  response-timeout: 5000
  # (optional) address from cluster to gateway
  gateway-address: ""
  # (optional) port from cluster to gateway
  gateway-port: 0

3、新建一个sqlLibs文件夹，里面添加jar包

cd /usr/local/service/flink-1.11.2

mkdir sqlLibs

   flink lib下的包如下：

  

4、kafka 新建topic，写入数据

#新建topic 
./kafka-topics.sh --zookeeper localhost:2181 --topic test_12 --partitions 1 --replication-factor 1 --create

#写入数据
./kafka-console-producer.sh --broker-list localhost:9092 --topic test_12
>tom,15
>jhon,21

#验证 是否写入，消费
./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test_12 --from-beginning

5、启动flink sql client：

cd /usr/local/service/flink-1.11.2

./sql-client.sh embedded  -d  ../conf/sql-client-defaults.yaml -l ../sqlLibs

6、创建表

CREATE TABLE mykafka_t (name String, age Int) WITH (
   'connector.type' = 'kafka',
   'connector.version' = 'universal',
   'connector.topic' = 'test_12',
   'connector.properties.bootstrap.servers' = '119.29.23.123:9092',
   'format.type' = 'csv',
   'update-mode' = 'append'
);

7、查询结果，一直往topic里面写数据

select * from mykafka_t;

写数据进去kafka

/usr/local/service/kafka/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test_12
>tom,15
>john,21
>sam,14

flink sql结果展示

bingo！！！终于完成了，你以为我一开始就是这么顺畅的嘛？怎么可能，下面才是重点呢，遇到的问题：

error1:

Flink SQL> select * from mykafka_t;
[ERROR] Could not execute SQL statement. Reason:
org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for 'org.apache.flink.table.factories.TableSourceFactory' in
the classpath.

Reason: Required context properties mismatch.

The matching candidates:
org.apache.flink.table.sources.CsvAppendTableSourceFactory
Mismatched properties:
'connector.type' expects 'filesystem', but is 'kafka'

The following properties are requested:
connector.properties.bootstrap.servers=119.29.23.123:9092
connector.topic=test_12
connector.type=kafka
connector.version=universal
format.type=csv
schema.0.data-type=VARCHAR(2147483647)
schema.0.name=name
schema.1.data-type=INT
schema.1.name=age
update-mode=append

The following factories have been considered:
org.apache.flink.table.sources.CsvBatchTableSourceFactory
org.apache.flink.table.sources.CsvAppendTableSourceFactory
org.apache.flink.table.filesystem.FileSystemTableFactory

solve: 缺少flink-connector-kafka_2.11-1.11.2.jar , flink-connector-kafka-base_2.11-1.11.2.jar ,flink-csv-1.11.2.jar

error2：

Flink SQL> select * from source_kafka4;
[ERROR] Could not execute SQL statement. Reason:
java.lang.ClassNotFoundException: org.apache.kafka.common.serialization.ByteArrayDeserialize

solve:缺少kafka-clients-2.4.1.jar
