Cassandra 3.0 不接受 Java 11 安装 [英] Cassandra 3.0 is not accepting Java 11 installation

问题描述

我正在尝试启动 Cassandra 3，但它给出了消息:

I am trying to launch Cassandra 3, but it gives message:

Cassandra 3.0 及更高版本需要 Java 8u40 或更高版本.

Cassandra 3.0 and later require Java 8u40 or later.

我安装了 Java 11.

I have Java 11 installed.

>java -version
java version "11.0.11" 2021-04-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.11+9-LTS-194)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.11+9-LTS-194, mixed mode)

JAVA_HOME 设置为此安装.

JAVA_HOME is set to this installation.

为什么 Cassandra 仍然要求 Java 8 或更高版本?

Why does Cassandra still asks for Java 8 or higher?

推荐答案

Cassandra 3.x 不支持 Java 11.只有 Cassandra 4.0 将支持 Java 11 - 请参阅 docs.您需要安装 Java 8 才能在您的机器上运行 Cassandra 才能运行 Cassandra 3.x

Cassandra 3.x doesn't support Java 11. Only Cassandra 4.0 will support Java 11 - see docs. You need to install Java 8 to run Cassandra on your machine to run Cassandra 3.x
