上面的简单代码就是我用来解码hdfs中flume接收的avro事件的代码。我遇到的问题是，在读取文件的第一个事件（正确打印）之后，我有一个例外：

显然，flume可能会在每个avro事件的末尾放置一个字符，并产生这个异常。
但是我找不到一个方法来正确地阅读它。
Flume配置如下：

tier1.channels = c1
tier1.sources = r1
tier1.sinks = k1
# AvroSource r1
tier1.sources.r1.channels = c1
tier1.sources.r1.type = avro
tier1.sources.r1.bind = 0.0.0.0
tier1.sources.r1.port = 60001
# Channel c1
tier1.channels.c1.type = file
# HdfsSink k1
tier1.sinks.k1.channel=c1
tier1.sinks.k1.type=hdfs
## HdfsSink k1 sinking properties
tier1.sinks.k1.hdfs.path=/
tier1.sinks.k1.hdfs.fileType = DataStream
tier1.sinks.k1.hdfs.batchSize = 100000
tier1.sinks.k1.hdfs.rollSize = 0
tier1.sinks.k1.hdfs.rollCount = 0
tier1.sinks.k1.hdfs.rollInterval = 60
tier1.sinks.k1.hdfs.threadPoolSize = 500
tier1.sinks.k1.hdfs.callTimeout = 180000
tier1.sinks.k1.hdfs.serializer = avro_event
tier1.sinks.k1.hdfs.writeFormat = Text
