Can't start Cassandra after OS patch up

Question

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

Exception (java.lang.AbstractMethodError) encountered during startup: org.apache.cassan         


        

Answer 1

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:

1. Download org.tar containing the only class to be replaced.
2. Untar the file using tar -xvf org.tar and you should get org directory
3. Copy the apache-cassandra jar file. e.g. cp /usr/share/cassandra/apache-cassandra-3.11.1.jar .
4. Make a backup of the jar before you update. cp apache-cassandra-3.11.1.jar apache-cassandra-3.11.1.jar_backup.
5. Expecting the current directory contains the following files: apache-cassandra-3.11.1.jar apache-cassandra-3.11.1.jar_backup org org.tar

6. Execute the following command to update the jar:

   jar uf apache-cassandra-3.11.1.jar org

7. Replace the file to installation location:

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

8. Restart cassandra service

Answer 3

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.

Answer 4

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.
