安装jdk9
后,我一直在看到这个问题:
$hive
Java HotSpot(TM) 64-Bit Server VM warning: Ignoring option MaxPermSize; support was removed in 8.0
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/Cellar/hive/2.3.1/libexec/lib/log4j-slf4j-impl-2.6.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]

但我有
更新$PATH
以指向java8
$java -version
java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)
更新hive
可执行文件以指定java8
vi $(which hive)
#!/bin/bash
JAVA_HOME="$(/usr/libexec/java_home --version 1.8)" HIVE_HOME="/usr/local/Cellar/hive/2.3.1/libexec" exec "/usr/local/Cellar/hive/2.3.1/libexec/bin/hive" "$@"
已验证更新的java版本确实指向jdk8
$/usr/libexec/java_home --version 1.8
/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home
我还应该在这里讨论什么?
这是hive 2.3.1
macos
$hive --version
Hive 2.3.1

安装jdk8并在hadoop-env.sh中相应地更改路径,这对我有用。

我遇到同样的问题,我只是删除了JDK 9而不是改变环境,问题就解决了。
请参阅hive,它使用
JAVA_HOME="$(/usr/libexec/java_home --version 1.7+)"
HIVE_HOME="/usr/local/Cellar/hive/2.3.1/libexec"
exec "/usr/local/Cellar/hive/2.3.1/libexec/bin/hive" "$@".

设置蜂巢时我遇到了同样的错误,起初我认为这可能是由于Java版本不同所致。
但是在检查Java版本时,它是jdk 1.8。
最后在检查jdk安装目录(/ Library / Java / JavaVirtualMachine)时,我发现同时存在jdk 1.8和jdk 10
我删除了jdk 10,终于奏效了。
