我正在尝试使用presto查询皮诺表数据，下面是我的配置详细信息。
started Pinot is one of the sit server.i.e. 10.184.160.52
Controller: 10.184.160.52:9000
server: 10.184.160.52:7000
broker: 10.184.160.52:8000
我在不同的服务器上有Presto端口是打开的，有这2台服务器。即10.184.160.53
Created One pinot.properties file inside presto/etc/catalog/pinot.properties.
connector.name=pinot
pinot.controller-urls=Controller_Host:9000
bin/launcher run ---> Loaded Pinot catalog.
Started Prestro with Pinot Segment.
./presto --server 10.184.160.53:8080 --catalog pinot
show catalogs;(able to see my Catalog)
pinot
show schemas; (able to see sachema also)
presto> show schemas;
Schema
--------------------
default
presto> use default;
USE
presto:default> show tables;----(able to see pinot tables:)
Table
------------------------------
test
test2
test3
(3 rows)
Query 20210519_124218_00061_vcz4u, FINISHED, 1 node
Splits: 19 total, 19 done (100.00%)
0:00 [3 rows, 98B] [10 rows/s, 340B/s]
但当我从测试中选择*时；其显示经纪人未找到
presto:default> select * from test;
Query 20210519_124230_00062_vcz4u failed: No valid brokers found for test
完整的Presto日志：
Error Code PINOT_UNABLE_TO_FIND_BROKER (84213767)

我不明白这里发生了什么，为什么这个问题会出现在精选声明中。看起来皮诺经纪人不接受询问。someOne敬请建议，这里有什么问题。
更新：这是因为连接器不支持大小写混合的表名。支持大小写混合的列名。有一个pull请求添加对混合大小写表名称的支持：https://github.com/trinodb/trino/pull/7630
