Question

我在运行水槽代理时遇到问题（来自apache flume网站的基本示例）。我正在运行的命令是

./bin/flume-ng agent --conf conf --conf-file test.conf --name a1 -Dflume.root.logger=INFO,console

我的test.conf文件看起来像

# example.conf: A single-node Flume configuration

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444

# Describe the sink
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

我的env vars在这里：

TERM_PROGRAM=Apple_Terminal
SHELL=/bin/bash
TERM=xterm-256color

我得到的错误是

和

有人知道我可能缺少什么吗？

Answer 1

那太棒了。

我将说明显而易见的事：Java没有找到Flume库。

我正在搜索flume-ng脚本，看看为什么它没有正确的类路径。

Answer 2

从Cloudera工程师处获得此补丁/信息。去看看它是否解决了这个问题。 https://issues.apache.org/jira/secure/attachment/12628911/HBASE-10518.00.patch
