在嘗試訪問配置單元時啓動Presto服務器時出錯

Question

我試圖啓動Presto以在RHEL計算機上查詢配置單元。

但同時通過"./launcher run"啓動普雷斯托服務器，我收到以下錯誤：

3 errors 
com.google.inject.CreationException: Unable to create injector, see the following errors:

2) Error: Could not coerce value '8080 ' to int (property 'http-server.http.port') in order to call [public io.airlift.http.server.HttpServerConfig io.airlift.http.server.HttpServerConfig.setHttpPort(int)]

有幾件事情。您需要刪除「http-server.http.port = 8080」後的空格。

此外，您的node.id屬性無效。 node.id應匹配以下正則表達式：「[A-Za-z0-9] [_A-Za-z0-9 - ] *」（請參閱​​https://github.com/airlift/airlift/blob/1e5694fb13ac6ca9cbdae1a1e60909c62fc7a64e/node/src/main/java/io/airlift/node/NodeConfig.java#L30）。
