我正在研究從postgreSQL到HDFS的數據流 . 我在HDP 2.6沙箱上設置了融合環境 . 我對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-

連接的所有其他屬性也很好，我正在運行它

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

它工作正常，并根據數據庫中的表數創建主題

psql-table1

psql-table2

現在我想在所有主題上運行HDFS接收器，為postgreSQL數據庫中的每個表創建單獨的目錄 . 但是當我用命令運行HDFS接收器時

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

通過運行源我得到錯誤

如果我停止源連接并啟動接收器它工作正常 . 任何人都可以幫我，我可以設置多個水槽連接器 .
