JsonParseException:意外字符('<'(代码60)):预期有效值(数字,字符串,数组,对象,'true','false'或'null')

Question

我有一个程序,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更改为凤凰查询服务器以运行JUnit测试.我在属性文件中设置URL如下:

java.lang.RuntimeException: com.fasterxml.jackson.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.jackson.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] 

我不知道为什么我收到一个json解析异常.由于外部apis,调试没有帮助.我甚至不知道异常是否与我的属性文件中的URL格式,患者(以xml格式提供)或甚至与凤凰客户端相关.

我已经启动了凤凰查询服务器,看起来它可以连接到它,因为它之前抛出了"连接拒绝"异常,现在它没有.

我在我的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>

但我不知道是否必须为凤凰瘦客户端添加其他内容.如果必须的话,我找不到那种依赖关系,所以我只是假设它被包括在内.

任何帮助表示赞赏!

编辑:

这是服务器抛出的异常:

您是否正确升级了 Phoenix 服务器？看起来它尝试使用 JSON 和 Protocol Buffer 协议进行连接。应该是其中之一。
