错误代码 PINOT_UNABLE_TO_FIND_BROKER：未找到有效的经纪人

Question

我正在尝试使用 presto 查询 pinot table 数据，以下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安装了 Presto 端口已打开 b/w 这 2 个服务器。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]

但是当我做 select * from test 时；未找到其显示经纪人

presto:default> select * from test;
Query 20210519_124230_00062_vcz4u failed: No valid brokers found for test

我无法理解这里发生了什么，为什么 select statement.Looks 会出现这个问题，就像 pinot broker 不接受 queries.someOne 请建议，这里的问题是什么.

Answer 1

更新：这是因为连接器不支持大小写混合 table 名称。支持大小写混合的列名。有一个拉取请求以添加对混合大小写 table 名称的支持：https://github.com/trinodb/trino/pull/7630
