我试图在没有任何成功的情况下运行kafka-connect-hdfs。
我已将以下行添加到.bash_profile并运行'source〜/.bash_profile'
export LOG_DIR=~/logs
QuickStart-HDFS.Properties配置文件是
name=hdfs-sink
connector.class=io.confluent.connect.hdfs.HdfsSinkConnector
tasks.max=1
hdfs.url=xxx.xxx.xxx.xxx:xxxx # placeholder
flush.size=3
hadoop.conf.dir = /etc/hadoop/conf/
logs.dir = ~/logs
topics.dir = ~/topics
topics=test_hdfs
我正在遵循Quickstart指令https://docs.confluent.io/current/connect/connect-hdfs/docs/hdfs_connector.html
连接器 - avro-stanalone.properties文件的内容是：
bootstrap.servers=yyy.yyy.yyy.yyy:yyyy # This is the placeholder for the Kafka broker url with the appropriate port
key.converter=io.confluent.connect.avro.AvroConverter
key.converter.schema.registry.url=http://localhost:8081
value.converter=io.confluent.connect.avro.AvroConverter
value.converter.schema.registry.url=http://localhost:8081
internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
offset.storage.file.filename=/tmp/connect.offsets
我有Quickstart-HDFS.properties和Connector-avro-Stanalone.properties在我的主目录中，我运行：
confluent load hdfs-sink -d quickstart-hdfs.properties
我不确定如何访问我的主目录中的连接器 - avro-stanalone.properties文件中的信息。
当我运行时：'Confluent Log Connect'，我会收到以下错误：

解决此问题的任何帮助将不胜感激。
引起的：
您需要hdfs.url=hdfs://xxx.yyy.zzz.abc以及Namenode端口
另外，您需要删除属性文件中等等符号周围的空格
