使用：
- Java 1.8.0_231
- Hadoop 3.2.1
- 水槽1.8.0
已在9000端口上创建了hdfs服务。
jps：
11688 DataNode
10120 Jps
11465 NameNode
11964 SecondaryNameNode
12621 NodeManager
12239 ResourceManager
Flume conf：
agent1.channels.memory-channel.type=memory
agent1.sources.tail-source.type=exec
agent1.sources.tail-source.command=tail -F /var/log/nginx/access.log
agent1.sources.tail-source.channels=memory-channel
#hdfs sink
agent1.sinks.hdfs-sink.channel=memory-channel
agent1.sinks.hdfs-sink.type=hdfs
agent1.sinks.hdfs-sink.hdfs.path=hdfs://cluster01:9000/system.log
agent1.sinks.hdfs-sink.hdfs.fileType=DataStream
agent1.channels=memory-channel
agent1.sources=tail-source
agent1.sinks=log-sink hdfs-sink
然后开始水槽：
./bin/flume-ng agent --conf conf -conf-file conf/test1.conf --name agent1 -Dflume.root.logger=INFO,console
然后遇到错误：

我搜索了一段时间，但没有在网上找到相同的错误。有解决此问题的建议吗？
