Presto：连接器“mysql”没有工厂

Question

我在做

$ ./launcher run

下面的错误信息是get generate

java.lang.IllegalArgumentException: No factory for connector 'mysql'. Available factories: [memory, kudu, blackhole, kinesis, redis, accumulo, gsheets, raptor-legacy, elasticsearch, jmx, postgresql, redshift, sqlserver, localfile, tpch, iceberg, bigquery, memsql, prometheus, mongodb, example-http, pinot, tpcds, oracle, phoenix, system, cassandra, kafka, atop, hive-hadoop2, presto-thrift]

at io.prestosql.server.PrestoServer.main(PrestoServer.java:39)

这是我的“mysql.properties”文件

connector.name=mysql
connection-url=jdbc:mysql://127.0.0.1:3306
connection-user=root
connection-password=onkar@77

有人可以帮忙吗..拜托

Answer 1

您需要将“datasource.driver”添加到您的“mysql.properties”文件中。

Answer 2

mysql 插件绝对是 Presto 336 的一部分，您正在使用的版本。

我会假设 <presto-install-dir>/plugin/mysql 目录在本地安装时以某种方式被删除。
