無法連接，因爲動物園管理員

Question

爲到HBase的連接到HBase的我寫這樣的代碼：

Class.forName("com.salesforce.phoenix.jdbc.PhoenixDriver"); 
      conn = DriverManager.getConnection("jdbc:phoenix:localhost:2181"); 

但運行給我這個錯誤後：

我不明白是什麼問題。 我單獨安裝hbase 0.94.10和zookeeper 3.4.5，我不確定配置是否正確。您可以引導並幫助我如何正確配置它們

Answer 1

您確定要複製鳳凰服務器jar（它的名爲only phoenix -.jar，我認爲它應該是phoenix-2.0.0.jar在你的情況下）到所有的區域服務器？ 還要確保phoenix jar的位置被附加到HBase類路徑。你需要把下面也許在所有區域服務器的hbase-env.sh：

HBASE_CLASSPATH=$HBASE_CLASSPATH:/path/to/phoenix-2.0.0.jar 

之後，您需要重新啓動集羣。然後鳳凰會工作。 您也可以閱讀其安裝指南github project page。 更新： 我剛纔看到他們更新了他們的文檔。文檔THW的最後一個版本更straigh進，但我想你會管理...

Answer 2

添加答案的人仍在尋找：

你的JDBC連接字符串必須是這樣的：

jdbc：phoenix：zookeeper_quorum：2181：/ hbase_znode 或;

的jdbc：鳳：zookeeper_quorum：/ hbase_znode

（默認情況下，飼養員會偵聽端口2181）

zookeeper_quorum - 可以是逗號分隔的服務器名稱（必須是完全合格的DNS名稱） hbase_znode - hbase或hbase-unsecured

eg

JDBC：鳳：server1.abc.com，server2.abc.com：2181：/ HBase的
