將hbase-client與Google Cloud Bigtable結合使用時出現錯誤

Question

我無法通過Java調用Google Cloud Bigtable上的任何操作。

我不斷收到此錯誤：

這是生成此錯誤的測試代碼：

    try {
        Connection connection = BigTableHelper.getConnection();
        Table table = connection.getTable(TableName.valueOf("Tango"));

        byte[] rowKey = Bytes.toBytes("username");
        Put p = new Put(rowKey);
        p.addColumn(Bytes.toBytes("O"), Bytes.toBytes("acme"), Bytes.toBytes("sync"));
        LOGGER.trace("Putting to row {}", Bytes.toStringBinary(rowKey));
        table.put(p);
    } catch (IOException e) {
    }

有人知道可能會關閉連接嗎？ 我沒有明確關閉連接，甚至嘗試將put操作放到ThreadPoolExecutor中以將其與主Controller線程隔離開，但無濟於事。

Answer 1

我們尚未對Tomcat進行測試。

為了使Jetty運行，我必須將alpn-boot添加到jetty JAVA執行行中，然后將alpn-boot添加到Servlet類加載器的系統類列表中。

您的堆棧跟蹤中沒有任何東西表明這是問題所在，但是，這將是我第一次看到的地方。

gRPC使用的http / 2需要Alpn。 即使它是Jetty項目的一部分，您還是需要Tomcat。

alpn-boot的版本會根據您使用的Java的次要版本進行更改。 （即，對於Java7，大約有4個jar，對於Java8，也差不多。）
