操作系统补丁后无法启动Cassandra

When I try to start Cassandra after patching my OS, I get this error:

当我在修补我的操作系统后尝试启动Cassandra时，我收到此错误：

Exception (java.lang.AbstractMethodError) encountered during startup: org.apache.cassandra.utils.JMXServerUtils$Exporter.exportObject(Ljava/rmi/Remote;ILjava/rmi/server/RMIClientSocketFactory;Ljava/rmi/server/RMIServerSocketFactory;Lsun/misc/ObjectInputFilter;)Ljava/rmi/Remote;

Does anyone know why, with no other changes, I'm running into this error now?

有没有人知道为什么，没有其他变化，我现在遇到这个错误？

4 个解决方案

#1

This seems to relate to an upgrade to the JDK to 8u161 which was released 2 days ago.

这似乎与2天前发布的JDK升级到8u161有关。

A ticket has been opened on the Cassandra Jira

Cassandra Jira开了一张票

There is no published work-around that I can find. You might have to go back to an earlier version of the JDK or wait for Cassandra 3.11.2 which fixes the issue.

我找不到已发表的解决方法。您可能必须返回到JDK的早期版本或等待修复该问题的Cassandra 3.11.2。

Edit: Its worth pointing out that this has now been resolved in 3.11.2 which has been released, so you can simply upgrade to this version to resolve the problem.

编辑：值得指出的是，这已经在已发布的3.11.2中得到解决，因此您只需升级到此版本即可解决问题。

To get Cassandra running I had to install JDK 8u152. Using brew cask install java8 it wasn't possible. I tried using an old version of the cassandra.rb formula but that just got:

为了让Cassandra运行，我必须安装JDK 8u152。使用brew cask安装java8是不可能的。我尝试使用旧版本的cassandra.rb公式，但刚刚得到：

Error: Download failed on Cask 'java8' with message: Download failed: http://download.oracle.com/otn-pub/java/jdk/8u152-b16/aa0333dd3019491ca4f6ddbe78cdb6d0/jdk-8u152-macosx-x64.dmg

I had to go here and log in to be able to download the DMG: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html

我必须去这里登录才能下载DMG：http：//www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html

Protip: To still be able to install java8 using homebrew I downloaded the dmg myself, and started a server in the downloads directory:

Protip：仍然能够使用自制软件安装java8我自己下载了dmg，并在downloads目录中启动了一个服务器：

cd ~/Downloads
php -S 0.0.0.0:3333

And changed the download URL (line 6) in the formula to:

并将公式中的下载URL（第6行）更改为：

url "http://0.0.0.0:3333/jdk-8u152-macosx-x64.dmg",

Then was able to run:

然后能够运行：

brew cask install java8

Now Cassandra is running again.

现在Cassandra又跑了。

You may download the source and add the changed method, compile and add the modified class to the apache-cassandra.jar. You can do the following:

您可以下载源并添加更改的方法，编译并将修改后的类添加到apache-cassandra.jar。您可以执行以下操作：

Download org.tar containing the only class to be replaced.
下载包含唯一要替换的类的org.tar。
Untar the file using tar -xvf org.tar and you should get org directory
使用tar -xvf org.tar解压缩文件，你应该获得org目录
Copy the apache-cassandra jar file. e.g. cp /usr/share/cassandra/apache-cassandra-3.11.1.jar .
复制apache-cassandra jar文件。例如cp /usr/share/cassandra/apache-cassandra-3.11.1.jar。
Make a backup of the jar before you update. cp apache-cassandra-3.11.1.jar apache-cassandra-3.11.1.jar_backup.
在更新之前备份jar。 cp apache-cassandra-3.11.1.jar apache-cassandra-3.11.1.jar_backup。
Expecting the current directory contains the following files: apache-cassandra-3.11.1.jar apache-cassandra-3.11.1.jar_backup org org.tar
期望当前目录包含以下文件：apache-cassandra-3.11.1.jar apache-cassandra-3.11.1.jar_backup org org.tar
Execute the following command to update the jar:

执行以下命令更新jar：

jar uf apache-cassandra-3.11.1.jar org

jar uf apache-cassandra-3.11.1.jar org
Replace the file to installation location:

将文件替换为安装位置：

mv apache-cassandra-3.11.1.jar /usr/share/cassandra

mv apache-cassandra-3.11.1.jar / usr / share / cassandra
Restart cassandra service

重启cassandra服务

change line 6 URL as suggested url "http://127.0.0.1:3333/jdk-8u152-macosx-x64.dmg",

按建议的URL更改第6行URL“http://127.0.0.1:3333/jdk-8u152-macosx-x64.dmg”，
