Question

将事件从一个服务传递到另一个服务时遇到问题。当我禁用SSL时，我的事件在另一端正确接收。但是当我启用SSL时，我得到了例外情况。

我正在使用apache flume 1.6（最新）

我的疑惑是：

agent.sources.ashok-source.type = avro
agent.sources.ashok-source.channels = ashok-channel
agent.sources.ashok-source.bind = 192.168.168.197
agent.sources.ashok-source.port = 41422
agent.sources.ashok-source.ssl = true
agent.sources.ashok-source.keystore = S:/Ashok/keystore/ashokKeystore.jks
agent.sources.ashok-source.keystore-password = ashok-123
agent.sources.ashok-source.keystore-type = jks
agent.sinks.ashok-sink.type = com.ashok.sink.AshokSink
agent.sinks.ashok-sink.channel = ashok-channel
agent.sinks.ashok-sink.ssl = true
agent.sinks.ashok-sink.truststore = S:/Ashok/keystore/ashokKeystore.jks
agent.sinks.ashok-sink.truststore-password = ashok-123
agent.sinks.ashok-sink.truststore-type = JKS
agent.channels.ashok-channel.type = file
agent.channels.ashok-channel.checkpointDir = ../channel/ashok/checkpoint
agent.channels.ashok-channel.dataDirs = ../channel/ashok/data

我的代码：

RpcClient client = null;
try {
        client = RpcClientFactory.getDefaultInstance("192.168.168.197", 41422);
        Map<String, String> header = new HashMap<String, String>();
        header.put("head", "er");
        Event event = EventBuilder.withBody(ByteArrayUtil.getBytes("Data"), header);
        client.append(event);
    } catch (Exception e) {
        e.printStackTrace();
    }

我使用以下链接创建了我的JKS文件。 https://www.sslshopper.com/article-how-to-create-a-self-signed-certificate-using-java-keytool.html

我做错了可以有人帮助我。

Answer 1

我没有使用RpcClientFactory.getDefaultInstance("192.168.168.197", 41422);，而是在运行时使用RpcClientFactory.getInstance(properies)和truststore属性修复了我的问题。

Map<String, String> header = new HashMap<String, String>();
TransTO transTO = new TransTO(1, "Ashok", true);
header.put("print", "yes");
Event event = EventBuilder.withBody(ByteArrayUtil.getBytes(transTO), header);
Properties prop = new Properties();
prop.setProperty("hosts.h1", "192.168.2.62:41422");
prop.setProperty("hosts", "h1");
prop.setProperty("compression-type", "deflate");
prop.setProperty("truststore-type", "JKS");
prop.setProperty("ssl", "true");
prop.setProperty("truststore", "D:/New folder/cacerts.jks");
prop.setProperty("truststore-password", "ashok-123");
RpcClient client = RpcClientFactory.getInstance(prop);
client.append(event);

您需要在RPC客户端

中设置ssl属性为true

Avro协议中的Flume SSL问题
