尝试在 Intellij 中启动 Presto 服务器时，我总是遇到此错误。

我使用 brew 安装了 mysql。

Answer 1

当每个 Presto 服务器启动时，它会记录加载了哪些目录。我的猜测是文件不在正确的位置，或者您没有重新启动 Presto 服务器。请注意，该文件必须在每个 Presto 服务器上。

Answer 2

'mysql.properties' 文件应该存在于 presto-main/etc/catalog 文件夹

此外， 'presto-main/etc/config.properties' 应该被编辑。 '../presto-mysql/pom.xml' 需要附加在 plugin.bundles 中，如下所示

$ cat presto-main/etc/config.properties

# sample nodeId to provide consistency across test runs
node.id=ffffffff-ffff-ffff-ffff-ffffffffffff
node.environment=test
http-server.http.port=8080

discovery-server.enabled=true
discovery.uri=http://localhost:8080

exchange.http-client.max-connections=1000
exchange.http-client.max-connections-per-server=1000
exchange.http-client.connect-timeout=1m
exchange.http-client.read-timeout=1m

scheduler.http-client.max-connections=1000
scheduler.http-client.max-connections-per-server=1000
scheduler.http-client.connect-timeout=1m
scheduler.http-client.read-timeout=1m

query.client.timeout=5m
query.max-age=30m

plugin.bundles=\
  ../presto-raptor/pom.xml,\
  ../presto-hive-cdh4/pom.xml,\
  ../presto-example-http/pom.xml,\
  ../presto-kafka/pom.xml,\
  ../presto-tpch/pom.xml,\
  ../presto-mysql/pom.xml
