Kafka MongoDB 接收器连接器错误！没有开始

Question

我正在尝试在 Linux Ubuntu 20.04 上将 Kafka 与 MongoDB 连接，以前它工作正常，但现在我在运行时遇到错误。

这是我尝试将 Kafka 与 MongoDb 连接起来的方式。

我制作了一个单独的 connect-standalone_bare.properties 文件，其中包含以下实体：

# The converters specify the format of data in Kafka and how to translate it into Connect data. Every Connect user will
# need to configure these based on the format they want their data in when loaded from or stored into Kafka
key.converter=org.apache.kafka.connect.json.JsonConverter
value.converter=org.apache.kafka.connect.converters.JsonConverter
# Converter-specific settings can be passed in by prefixing the Converter's setting with the converter we want to apply
# it to
key.converter.schemas.enable=false
value.converter.schemas.enable=false
rest.port:8084

offset.storage.file.filename=/tmp/connect.offsets-1
# Flush much faster than normal, which is useful for testing/debugging
offset.flush.interval.ms=10000

# Set to a list of filesystem paths separated by commas (,) to enable class loading isolation for plugins
# (connectors, converters, transformations). The list should consist of top level directories that include 
# any combination of: 
# a) directories immediately containing jars with plugins and their dependencies
# b) uber-jars with plugins and their dependencies
# c) directories immediately containing the package directory structure of classes of plugins and their dependencies
# Note: symlinks will be followed to discover dependencies or plugins.
# Examples: 
# plugin.path=/usr/local/share/java,/usr/local/share/kafka/plugins,/opt/connectors,
plugin.path=/home/ms-batch18/Documents/kafka_2.13-2.8.0/libs/mongo-kafka-connect-1.2.0-all.jar

这是我的 MongoDb 接收器连接器：

name=mongo-sink
topics=test
connector.class=com.mongodb.kafka.connect.MongoSinkConnector
tasks.max=1
key.ignore=true
connection.uri=mongodb://localhost:27017
database=test_kafka
collection=transaction
max.num.retries=3
retries.defer.timeout=5000
type.name=kafka-connect
schemas.enable=false

运行此命令时：

bin/connect-standalone.sh config/connect-standalone_bare.properties config/MongoSinkConnector.properties

我正面临这个错误：

错误是说你提供的属性文件在你的 shell 的相对路径中不存在。

给出绝对路径来验证它是否存在。

也建议改用connect-distributed
