我有一个使用apache Hadoop 2.10.0，hbase 1.5和Phoenix 4.14的设置。一切正常。但是，当我尝试将python与Phoenix连接时，我需要启用queryserver。每当我尝试启动时，都会出现以下错误并退出。有人可以帮忙吗？

最佳答案
默认情况下不包括Phoenix Query Server。这是一个单独的jar phoenix-queryserver，需要包含在类路径中:
https://mvnrepository.com/artifact/org.apache.phoenix/phoenix-queryserver/4.14.3-HBase-1.4
关于java - 错误:启动Apache Phoenix Queryserver时找不到或加载主类org.apache.phoenix.queryserver.server.QueryServer，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/62135438/
