JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
提问by randombee
I have a program that inserts a new patient to HBase in a docker container inside a server. Everything is working fine until I try to change the connection IP to a phoenix query server for running JUnit tests. I am setting the URL in the properties file like this:
我有一个程序可以在服务器内的 docker 容器中将新患者插入 HBase。一切正常，直到我尝试将连接 IP 更改为 phoenix 查询服务器以运行 JUnit 测试。我在属性文件中设置 URL，如下所示：
java.lang.RuntimeException: com.fasterxml.Hymanson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
at [Source: java.io.StringReader@1105b1f; line: 1, column: 2]
...
Caused by: com.fasterxml.Hymanson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at [Source: java.io.StringReader@1105b1f; line: 1, column: 2]
I am not sure why I'm receiving a jsonparse exception. Because of the external apis, debugging didn't help. I don't even know if the exception is related to the format of the URL in my properties file, to the patient (which comes in xml format) or maybe even to the phoenix client.
我不确定为什么我会收到json解析异常。由于外部 api，调试没有帮助。我什至不知道异常是否与我的属性文件中的 URL 格式、患者（以 xml 格式出现）或什至与 phoenix 客户端有关。
I have started the phoenix query server and it looks like it can connect to it, because it was throwing a "connection refused" exception before and now it doesn't.
我已经启动了 phoenix 查询服务器，看起来它可以连接到它，因为它之前抛出了“连接被拒绝”异常，现在它没有。
I added phoenix in my pom.xml like this:
我在 pom.xml 中添加了 phoenix，如下所示：
<dependency>
<groupId>org.apache.phoenix</groupId>
<artifactId>phoenix-server</artifactId>
<version>4.7.0-HBase-1.1</version>
</dependency>
but I don't know if I have to add something else for the phoenix-thin-client. If I have to, I couldn't find that dependency, so I just assumed it's included.
但是我不知道我是否必须为凤凰瘦客户端添加其他内容。如果必须的话，我找不到该依赖项，所以我只是假设它已包含在内。
Any help is appreciated!
任何帮助表示赞赏！

This is the exception the server throws:
这是服务器抛出的异常：

Did you upgrade your Phoenix server properly? It looks like it trying to use both the JSON and Protocol Buffer protocols to connect. It should be one or the other.
您是否正确升级了您的凤凰服务器？看起来它试图同时使用 JSON 和协议缓冲区协议进行连接。它应该是其中之一。
