设置多个kafka连接接收器

我正在研究从postgreSQL到HDFS的数据流 . 我在HDP 2.6沙箱上设置了融合环境 . 我对postgreSQL的jdbc源配置是

name=jdbc_1
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.url=jdbc:postgresql://host:port/db?currentSchema=schema&user=user&password=password
mode=timestamp
timestamp.column.name=col1
validate.non.null=false
topic.prefix=psql-

连接的所有其他属性也很好，我正在运行它

./bin/connect-standalone ./etc/kafka/connect-standalone.properties ./etc/kafka-connect-jdbc/source.properties

它工作正常，并根据数据库中的表数创建主题

psql-table1
psql-table2

现在我想在所有主题上运行HDFS接收器，为postgreSQL数据库中的每个表创建单独的目录 . 但是当我用命令运行HDFS接收器时

./bin/connect-standalone ./etc/kafka/connect-standalone.properties ./etc/kafka-connect-hdfs/hdfs-postGres.properties

通过运行源我得到错误

如果我停止源连接并启动接收器它工作正常 . 任何人都可以帮我，我可以设置多个水槽连接器 .
