在使用水槽(1.6& 1.7)时,我遇到以下错误

我的代理管道设置为从spooldir源获取json数据,使用morphline拦截器提取和转换。
参见下面的水槽配置摘录
#GENERIC
a1.channels = mem-channel
a1.sources = r2
a1.sinks = k2 k3
#CHANNEL
a1.channels.mem-channel.type = memory
a1.channels.mem-channel.capacity = 10000000
a1.channels.mem-channel.transactionCapacity = 1000
#SRC
a1.sources.r2.type = spooldir
a1.sources.r2.channels = mem-channel
a1.sources.r2.spoolDir = /path/to/some/directory
a1.sources.r2.interceptors = morphline
#INTERCEPTOR
a1.sources.r2.interceptors.morphline.type = org.apache.flume.sink.solr.morphline.MorphlineInterceptor$Builder
a1.sources.r2.interceptors.morphline.morphlineFile =/some/morphline/forex.conf
a1.sources.r2.interceptors.morphline.morphlineId = convertJsonToCSV
#SINK
a1.sinks.k2type = logger
a1.sinks.k2.channel = mem-channel
a1.sinks.k3.type = file_roll
a1.sinks.k3.channel = mem-channel
a1.sinks.k3.sink.directory = /tmp/flume
a1.sinks.k3.batchSize = 1
答案 0 :(得分:1)

答案一直盯着我。问题是不 morphline配置和输入子文件。 仔细看看水槽警告线
[WARN - org.apache.flume.serialization.LineDeserializer.readLine(LineDeserializer.java:143)] Line length exceeds max (2048), truncating line!
为解决方案提供了良好的指导。默认的spooldir源使用deserialiser.LINE
。它有一个参数deserializer.maxLineLength
,默认值为2048.从Flume用户指南中,此参数定义为
单个事件中包含的最大字符数。如果一行超过此长度,则会被截断,并且该行上的其余字符将出现在后续事件
中
无法解析JSON对象,因为数据内容在假脱机处理时被截断,这使得morphline处理JSON字节数组读取时不完整。

我将deserializer.maxLineLength
的值增加到10000(为了安全,因为我的子文件中的字符数量将来会很大)。
