My log configuration file:

a1.sources = r1
a1.channels = c1
a1.sinks = k1

Describe/configure the source

a1.sources.r1.type = TAILDIR
#断点续传
#a1.sources.r1.positionFile = D:\flumedev\tail_dir.json

多目录监控

a1.sources.r1.filegroups = f1 f2
a1.sources.r1.filegroups.f1 = D:\flumedev\source\test2\asdfile.log
a1.sources.r1.filegroups.f2 = D:\flumedev\source\test1\test.log

channal

a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

Describe the sink

a1.sinks.k1.type = logger

Bind the source and sink to the channel

a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

My startup Flume command:
D:\apache-flume-1.11.0-bin>bin\flume-ng agent --conf conf --conf-file D:\flumedev\flume-taildir-hdfs.conf --name a1

The error logs I received:
