When I try to start Cassandra after patching my OS, I get this error:
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?
回答1:
This seems to relate to an upgrade to the JDK to 8u161 which was released 2 days ago.
A ticket has been opened on the Cassandra Jira
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.
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.

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:
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
Protip: To still be able to install java8 using homebrew I downloaded the dmg myself, and started a server in the downloads directory:
cd ~/Downloads
php -S 0.0.0.0:3333
And changed the download URL (line 6) in the formula to:
url "http://0.0.0.0:3333/jdk-8u152-macosx-x64.dmg",
Then was able to run:
brew cask install java8
Now Cassandra is running again.

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:
- Download org.tar containing the only class to be replaced.
- Untar the file using
tar -xvf org.tar
and you should getorg
directory - Copy the apache-cassandra jar file. e.g.
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
. - Expecting the current directory contains the following files:
apache-cassandra-3.11.1.jar apache-cassandra-3.11.1.jar_backup org org.tar
Execute the following command to update the jar:
jar uf apache-cassandra-3.11.1.jar org
Replace the file to installation location:
mv apache-cassandra-3.11.1.jar /usr/share/cassandra
Restart cassandra service

Revert Cask formula to 2017 version.
wget https://github.com/caskroom/homebrew-versions/blob/a98da98a7e4d87e9b614b3aa25af9c6c21a753c6/Casks/java8.rb -O /usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks/java8.rb
change line 6 URL as suggested url "http://127.0.0.1:3333/jdk-8u152-macosx-x64.dmg",
brew cask reinstall java8
should work.
