Kafka-Connectを起動できません

Question

"./bin/connect-standalone ./etc/kafka/connect-standalone.properties ./etc/kafka"コマンドでkafka-connectを起動すると、次のエラーが表示されます。 -connect-elasticsearch/quickstart-elasticsearch.properties」を参照してください。そのため、kafka-connectは正しく起動できません。以下は

connect-standalone.propertiesファイルの内容れる：以下

tasks.max=2 
topics=compositionlog 
topic.index.map=compositionlog:compositionlog 
connection.url=http://10.104.185.143:9200

key.ignore=true 
schema.ignore=true 

についての任意のアイデア何が問題なの？

Answer 1

これは、Javaのバージョンの問題のように見える - あなたは正しいものを使用していることを確認してください - Javaの8
