Question

当我运行我的kafka连接作业时，我收到以下错误

[2017-04-25 14:56:22,806] ERROR Failed to create job for ./etc/kafka-connect-jdbc/sqlserver.properties (org.apache.kafka.connect.cli.ConnectStandalone:88)

我的属性文件是

name=test-sqlserver-jdbc-autoincrement
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.url=jdbc:sqlserver://192.168.9.142:1433;databaseName=postilion;user=elasticsearch;password=elasticsearch
query=select convert(varchar(10), date_time, 120) as date,convert(char(12), 
date_time, 114) as time, * from support_notifications
mode=timestamp+incrementing
timestamp.column.name=date_time
incrementing.column.name=event_nr
topic.prefix=test-events

我尝试使用curl http://localhost:8083 /JdbcSourceConnector/config/validate对kafka connect（崩溃之前）进行 GET 调用，我得到了响应{"version":"0.10.2.0-cp1","commit":"64c9b42f3319cdc9"}curl: (3) <url> malformed。任何想法，因为这项工作在kafka 0.9中有效，我做错了。

所以我找到了出路。我最终在属性文件中将模式从时间戳+递增更改为递增，并删除了行 timestamp.column.name = DATE_TIME 即可。属性文件现在看起来像这样

name=test-sqlserver-jdbc-autoincrement
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.url=jdbc:sqlserver://192.168.9.142:1433;databaseName=postilion;user=elasticsearch;password=elasticsearch
query=select convert(varchar(10), date_time, 120) as date,convert(char(12), date_time, 114) as time, * from support_notifications
mode=incrementing
incrementing.column.name=event_nr
topic.prefix=postilion-events

kafka连接在0.9版中工作的作业在0.10.2中不起作用
