如何配置 Apache Spark 2.4.5 以連接到 HIVE 的 MySQL 元存儲？

Question

我正在嘗試使用HiveContext object 運行 Hive 查詢並收到以下錯誤：

Py4JJavaError

我已將hive-site.xml文件放在$SPARK_HOME/conf目錄中。 有沒有我錯過的步驟？ 尋找一些關於這個錯誤的信息。 我有一個用於 Hive 的 MySQL 元存儲，它在通過 Hive Z2591C98B70119FE65E9E4289 運行查詢時完美運行。

Answer 1

要將 hive mysql 元存儲配置為使用 spark，請將hive-site.xml從$HIVE_HOME/conf目錄復制到$SPARK_HOME/conf目錄並將以下屬性添加到文件。

<property>
   <name>hive.metastore.uri</name>
   <value>thrift://localhost:9083</value>
</property>

這使得外部應用程序可以通過 Thrift 服務器與 hive 進行交互。

然后，通過發出以下命令啟動 hive 元存儲服務器和 hiveserver2。

hive —-service metastore
hive —-service hiveserver2

現在，您應該可以從 spark 訪問 hive。
