告警描述

告警顯示，在類路徑下包含了多個(gè)SLF4J的綁定，然后選擇了一個(gè)實(shí)現(xiàn)類。

[root@hm hook-bin]# ./import-hive.sh
Using Hive configuration directory [/opt/software/apache-hive-3.1.0-bin/conf]
Log file for import is /opt/software/apache-atlas-2.1.0/logs/import-hive.log
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/opt/software/apache-hive-3.1.0-bin/lib/log4j-slf4j-impl-2.10.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/opt/software/hadoop-3.1.1/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]

如何解決

方案一

根據(jù)項(xiàng)目的實(shí)際情況，刪除多余的JAR包，多個(gè)JAR包路徑如下：

/opt/software/apache-hive-3.1.0-bin/lib/log4j-slf4j-impl-2.10.0.jar
/opt/software/hadoop-3.1.1/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar

方案二

查看項(xiàng)目的POM文件中是否有重復(fù)的SLF4J引入，如何查看？：

ROCKY@LAPTOP MINGW64 /d/02-工作空間/06-代碼空間/04-gitee/rills-atlas-2.1.0-rc3/addons/hive-bridge (master)
$ mvn dependency:tree

找到多余的SLF4J，然后將其排除：文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-764123.html
