Hive安装问题简述

發(fā)布時間：2025/4/5 编程问答 17 豆豆

生活随笔收集整理的這篇文章主要介紹了 Hive安装问题简述小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

??本文簡要介紹Hive安裝過程中的常見問題：版本下載地址、版本依賴、依賴jar包。重要的是，記錄Hive的元數據庫手動初始化時報錯的解決方案并對其進行反思

Hive的元數據庫手動初始化

當使用hive 2.x之前的版本時，也可以不做初始化，當 hive 進行第一次啟動時，會自動進行初始化，只是不會生成足夠多的元數據庫中的表，這些表需要在使用過程中慢慢生成。

如果使用的是Hive2.x版本，則Hive的元數據庫必須手動初始化。使用的命令和顯示界面如下：

在初始化元數據庫的過程中報錯

$cd /usr/local/java/hive/hive-2.1.0/bin # 進入hive安裝目錄 $./schematool -dbType mysql -initSchema # 對hive進行重新初始化

報錯信息如下：

hadoop@ubuntu16:/usr/local/java/hive-2.1.0/bin$ ./schematool -dbType mysql -initSchema SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/usr/local/java/hive-2.1.0/lib/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/usr/local/java/hadoop/hadoop-2.7.1/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification. org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version.

在啟動hive時報錯

hadoop@ubuntu16:/usr/local/java/hive-2.1.0/bin$ hive

報錯信息如下（僅截取部分報錯信息）：

hadoop@ubuntu16:/usr/local/java/hive-2.1.0/bin$ ./hive SLF4J: Class path contains multiple SLF4J bindings.

因為ubuntu的終端控制臺都是白色字體，而且輸出內容很多，很難找到報錯信息，因此可以根據報錯信息選擇一種類型的文件，將報錯信息存至文件中。因為hadoop、hive基于java語言，所以.java為后綴名的文件可以看到字體高亮。

在初始化hive元數據庫時，出現(xiàn)hive的報錯信息*** schemaTool failed ***

源于上面其他的錯誤信息：org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version.Underlying cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException : Communications link failure

將第一個報錯信息hive.metastore.HiveMetaException: Failed to get schema version.復制并在瀏覽器中搜索，尋找解決方法

解決方法：設置mysql時區(qū)，useSSL¹

<property><name>javax.jdo.option.ConnectionURL</name><value>jdbc:mysql://localhost:3306/db_hive?createDatabaseIfNotExist=true&serverTimezone=GMT&useSSL=false</value><description>JDBC connect string for a JDBC metastore</description> </property>

反思

先判斷在初始報錯處，應從源頭解決問題

將報錯信息的關鍵部分復制下來，精確搜索

長時間未解決可尋求他人幫助

Hive安裝過程中的其他問題

hive下載地址
APACHE官網: Index of /hive (apache.org)
推薦（版本較多）：華為云開源軟件鏡像網站-APACHE: Index of apache-local/hive (huaweicloud.com)

hadoop和hive版本對應關系
如：hive2.3.8 依賴于hadoop2.x.y，其他版本信息見：Downloads (apache.org)

News 17 January 2021: release 2.3.8 available This release works with Hadoop 2.x.y You can look at the complete JIRA change log for this release.

JDBC驅動下載 mysql-connector-java-x.y.z.jar
